Alexandru Dan Tudor (born 13 September 1971) is a retired Romanian football referee.

He took charge of a UEFA Cup first round match between Celta de Vigo and Odense Boldklub two months later, but it was not until 4 November 2008 that he refereed his first Champions League group stage match, when he officiated a match between Barcelona and Basel.

He refereed his last official match in the Romanian First Division on 14 December 2018, when he officiated a thrilling game between Concordia Chiajna and FC Politehnica Iași, 3-6.

Nicknamed Brad Pitt thanks to his looks, Tudor holds the record for the most games officiated in Liga 1, with over 380 matches under his badge.
