Embassy history

Find out more about the history of Ireland's presence in Mexico.

Diplomatic relations between Ireland and Mexico were established in 1975. In 2025 our two countries celebrate 50 years of this relationship.

Ireland did not have an Embassy in Mexico from 1975 to 1999. In this period, the Embassy of Ireland in the United States covered Mexico as a concurrent country of accreditation.

Throughout this time, the Embassy in Washington was ably assisted by Rómulo O’Farril, the Irish Honorary Consul of Ireland in Mexico from 1967 until 1999.

The Irish Ambassadors accredited to Mexico from Washington were:

Jack Molloy 1977-1978
Seán Donlon 1978-1981
Tadhg O'Sullivan 1981-1985
Patrick McKernan 1985-1991
Dermot Gallagher 1991-1997
Séan Ó Huiginn 1997-1999

Diplomatic relations between Ireland and Mexico continued to intensify. In 1991 Mexico opened a resident Embassy in Dublin and in 1999 Ireland opened a resident Embassy in Mexico. The latter was preceded by a visit to Mexico by the then President of Ireland Mary McAleese.

Since that time 7 Irish Ambassadors have been accredited to Mexico:

Art Agnew 1999-2005
Dermot Brangan 2005-2009
Eamon Hickey 2009-2013
Sonja Hyland 2013-2017
Barbara Jones 2017-2020
Maeve von Heynitz 2021-2025
Ruairí de Búrca 2025-Present

The bilateral relationship continues to grow ever stronger across our political, economic, cultural and people to people links. The former President of Ireland, Mr. Michael D. Higgins, made an official visit to Mexico in October 2013.
