Tomás Taveira (born 1938) is a Portuguese architect. He is among Portugal's most highly-acclaimed architects born in the 20th century. He has a degree in architecture from the Technical University of Lisbon and owns a post-graduation from the MIT (U.S.A.). Three stadiums specially built for the UEFA Euro 2004 were designed by the architect Tomás Taveira.

Tomás Taveira's emblematic buildings include:

In the 1980s he was involved in a sex scandal when some personal home-made recordings were found in videotapes and sent to the Portuguese magazine Semana Ilustrada. The recordings showed him having sexual intercourse and rough anal sex with different younger women inside his office at Amoreiras, Lisbon. Since then he gained huge notoriety. The Spanish magazine Interviú also published photos of the recorded scenes which prompted Taveira's lawyer to request court action against the magazines.

The infamous recordings with hardcore sexual content were made available in VHS tapes that spread to the general public and later on peer-to-peer networks. Due to this scandal and related negative publicity, Taveira faced personal and professional setbacks until the late 1990s.
