Domingo Bernardo de Bonechea Andonaegui (21 September 1713 – 26 January 1775) was a Spanish Navy officer and explorer.
His younger brother Francisco Bonechea Andonaegui was also a naval officer, mentioned as a lieutenant aboard one of the frigates that escorted Carlos III from Italy to Spain in 1759 on his accession to the Spanish throne and died in Puerto Caballo in 1761.
After a desperate action on June 28 against the British Captain George Mackenzie he surrendered at Mariel together with the Virganza (24) commanded by Diego Argote.
He sailed with Tomás Gayangos as his lieutenant on the Aguila, Santa Maria Magdalena, from Callao harbour, Peru, and reached Tahiti on 7 Nov.
The aim of this expedition was the annexation of Tahiti to the Spanish crown, with the approval and encouragement of King Carlos III, and to convert its inhabitants.
