Wahaca (phonetic spelling of the Mexican State of Oaxaca) is a UK restaurant group selling Mexican-style street food, co-founded by Thomasina Miers, with 14 branches in the United Kingdom.

Miers opened the first branch in Chandos Place, London in August 2007, focused on Mexican street food.

[7] In November 2017, Wahaca used the Mexican holiday Day of the Dead as the basis for a three-day festival to promote their business.

[8][9][10] In August 2020, Wahaca announced that it would close ten of its 28 restaurants due to a downturn in business caused by the coronavirus pandemic.

[12] In November 2020, Dick Enthoven, owner of Nandos, bought a £4m majority stake in Wahaca's parent company, Oaxaca Ltd. Wahaca entered into a Company Voluntary Arrangement (CVA), in which shareholders and lenders agreed to write off £25m of debt while injecting £5m into the restaurant chain.
