Best Advertising Agencies in Buenos Aires (2026)

Introduction

Buenos Aires has one of the strongest advertising scenes in Latin America, and the 9 agencies below are among the busiest in the city in 2026. Most are offices of the big holding companies, plus the Buenos Aires office of the US independent Tombras, which took a large share of recent effectiveness awards.

The local map moved a good deal over the past two years. Havas bought Don in February 2025 and merged it with its existing agency Hoy to form Don by Havas. Omnicom completed its acquisition of IPG at the end of 2025, bringing McCann’s two Buenos Aires agencies into the same group as TBWA, and is retiring the DDB and FCB brands during the first half of 2026. In June 2026 TBWA Buenos Aires said its local partners had bought back the majority stake from TBWA. At WPP, VML and Ogilvy in Argentina now share a chief executive, Emiliano Galván. On the awards side, VML Argentina led more winning cases than any other agency at Effie Argentina 2026.

Every agency here has an active Buenos Aires office in 2026, shown by its own site or by 2026 trade coverage of its local work. The list is unranked, since the right agency depends on the brief, the budget and how much regional work you need.

The best advertising agencies in Buenos Aires

1. Mercado McCann

McCann network (Omnicom) · Palermo · mccann.com

Mercado McCann is one of the two McCann agencies in Buenos Aires, working from Ángel J. Carranza in Palermo. It came into Omnicom with the rest of IPG at the end of 2025, and McCann is one of the three advertising networks Omnicom kept after its consolidation.

Its 2026 Effie Argentina winners include “Laureles” for TyC Sports and “Los convocados de NX” for Naranja X, and it was a finalist with several YPF campaigns and “Démosle pelota al autismo” for INECO.

2. McCann Buenos Aires

McCann network (Omnicom) · Palermo Hollywood · mccann.com

McCann Buenos Aires is the second McCann office in the city, on Costa Rica in Palermo Hollywood, separate from Mercado McCann. Like its sister agency, it became part of Omnicom when the IPG deal closed.

Its 2026 Effie Argentina shortlist entry was “El aire que todos queremos” for the air-conditioning brand BGH, in the seasonal marketing category. Brands that want McCann’s network but a smaller team than Mercado McCann’s can look at both and compare who would run the account.

3. TBWA Buenos Aires

Majority owned by local partners, in partnership with TBWA and Omnicom · Buenos Aires · tbwa.com

TBWA Buenos Aires has been led for about 15 years by Pablo Poncini, partner, CEO and chief creative officer, with partners Guillermo Castañeda and Juan Cruz Bazterrica as executive creative directors. In mid 2026 the partners bought back the majority stake from TBWA while staying in the TBWA and Omnicom network. The agency says about 60% of its work is for markets outside Argentina.

McDonald’s is the anchor client, covering Argentina and the Cajita Feliz (Happy Meal) brand across Central and South America, and its World Cup burgers campaign was among the Effie Argentina 2026 winners. Nissan runs through the agency regionally. New accounts in the past year include Alto Palermo (IRSA), the supermarket chain Coto, Evertec and ATH.

4. VML Argentina

WPP · Belgrano · vml.com

VML Argentina, the WPP agency formed from the merger of Wunderman Thompson and VMLY&R, works from Arribeños in Belgrano. It led five winning cases at Effie Argentina 2026, more than any other agency, three of them with Initiative Argentina.

The winners were “Cábalas” for Visa, “YPF, Yo siempre cargué acá” for YPF, and three Dove and Dove Men+Care campaigns for Unilever. Other recent work includes “Sharenting, the Musical” for Movistar and “Absurd Promises” for ASDRA, a Fast Company World Changing Ideas honoree for Latin America.

5. Ogilvy Argentina

WPP · Buenos Aires · ogilvy.com

Ogilvy Argentina shares its chief executive, Emiliano Galván, with VML, so the two WPP agencies are run together at the top while keeping separate brands. It had one of the longest finalist lists at Effie Argentina 2026, mostly for Unilever and Nestlé brands.

Winning cases include “No es un 10, es un Once” for Hellmann’s and “El tamaño de tu envidia” for the retailer Cetrogar, and it was shortlisted for Tang and Comfort. The agency’s site also shows work for Coca-Cola, Nestlé (Milo, Chamyto), SC Johnson and the supermarket chains Jumbo, Disco and Vea.

6. Grey Argentina

WPP · Belgrano · grey.com

Grey Argentina works from Avenida Franklin D. Roosevelt in Belgrano and is the third WPP creative brand in the city, alongside VML and Ogilvy.

Its 2026 Effie Argentina finalist was “Defendamos lo que es nuestro” for Coca-Cola, in the soft drinks category. Recent work on its site includes “The Postponed Day” for the cancer charity LALCEC, a chat-based campaign for Banco Itaú and work for Arroz Super Extra.

7. Don by Havas

Havas · Buenos Aires · havas.com

Don by Havas is the result of Havas buying Don, one of Argentina’s best-known independents, in February 2025 and merging it with Havas’s own agency Hoy. Co-founder Papón Ricciarelli leads it, and it works alongside Havas Media, Health and Production. Don also keeps an office in Mexico.

It had five shortlisted cases at Effie Argentina 2026, with winners for Yogurísimo, Mostaza and ICBC. La Serenísima added it to its agency roster in June 2026, and in July it launched “35 aeropuertos tan argentinos como su gente” for Aeropuertos Argentina, directed by Javier Nir and Fede Russo of Oruga Cine.

8. Digitas Argentina

Publicis Groupe · Buenos Aires · digitas.com.ar

Digitas Argentina is the Buenos Aires office of Digitas, Publicis Groupe’s connected-marketing network, which has 65 offices in 43 countries. Mercedes Alonzo is operations director.

Its Effie Argentina 2026 winner was “Garcé trajo alfajores” for Mondelez’s Shot. Case studies on its site include Beldent, Oreo, Visa and Cindor.

9. Tombras Buenos Aires

Independent · Buenos Aires · tombras.com

Tombras is an independent US agency headquartered in Knoxville, with Buenos Aires as one of its six offices alongside New York, Atlanta, Charlotte and Portland.

It led three winning cases at Effie Argentina 2026: “Congelar Rivales” for Jägermeister, “Crédito Uvas” for the AB InBev wine brand Dante Robino and “Empresabios” for Grupo Omint. It was also a finalist for Gatorade and Paso de los Toros.

What to look for in a Buenos Aires advertising agency

Start with the group behind the agency. Since the end of 2025 the city’s network offices sit with four main holding companies: Omnicom (McCann, Mercado McCann and TBWA), WPP (VML, Ogilvy and Grey), Havas and Publicis. That decides which media agency, production arm and regional network sit behind the creative team, and it matters most for brands buying media across several Latin American countries.

Ask how much of the agency’s work is for export. Several Buenos Aires agencies earn a large share of their revenue from other markets, which protects them from peso swings and brings in regional and US Hispanic accounts. It can also mean the senior team is split across clients in several countries, so ask who will be on your business week to week.

Look at effectiveness as well as creative awards. Effie Argentina is the clearest local measure of work that moved sales or share, and the 2026 shortlist shows which agencies are trusted with long-running brands such as Dove, McDonald’s, YPF and Fernet Branca. Lápiz de Oro, Diente and El Ojo de Iberoamérica are better guides to craft.

Finally, check how production and approvals are run. Buenos Aires agencies work closely with local production companies, and a single spot can pass through scripts, animatics, offline cuts and grades with clients in different cities. Agencies that keep every version in one place and gather client feedback in a structured way tend to lose fewer days between rounds.

How Fabric helps advertising agency teams

Fabric gives an agency one workspace for its files, client feedback and team knowledge, with AI search across all of it. The agency setup suits the account structure most Buenos Aires agencies run, with a space per client holding briefs, scripts, media plans, cuts and call notes.

Video files sit in Fabric’s cloud drive, which streams files on demand so they take no local disk space, and heavy edits open without a full download. Search works by meaning across documents, images and recordings, and transcription makes spots, interviews and casting tapes searchable, with results that jump to the right timestamp.

For review rounds, share a cut with the client and the production company with commenter access. They can open it through the shared link without signing up and leave timestamped comments on video and audio, draw on a video frame to point at a detail, or draw on a key visual and attach a note. The team marks each comment completed as it is fixed, so feedback works like a checklist. Annotations and collaboration cover how this works in detail.

For final delivery, any file or folder can be published as a web page, which is view-only, with optional download, and protected with a password. Link analytics shows when each named recipient opened a pitch deck or reel and how long they spent on it. On Team plans, self-writing docs keep a page for each client with decisions, deliverables and open items drawn from meetings, Slack and the workspace.

Password protection and link analytics are included on Pro and Team plans, and self-writing docs on Team plans. See plans for teams.
