Antonio Valdés y Fernández Bazán (25 March 1744 – 4 April 1816) was a Spanish navy officer of the Royal Navy.

He distinguished himself in the defence of Morro Castle and San Salvador de la Punta Fortress during the Battle of Havana (1762).

In 1781, he became director of the Royal Artillery Factory of La Cavada, and reorganised it to that extent that he was promoted to become inspector general of the Spanish Navy.

The settlements of Valdez, Alaska and Valdez, Florida were named after him, as well as Bazan Bay in Victoria, British Columbia, Canada.

The oil tanker Exxon Valdez, that gained notoriety after running aground in Prince William Sound spilling its cargo of crude oil into the sea on March 24, 1989, was named after the Alaskan town which had been named after Valdés.
