Roberto Trashorras Gayoso (born 28 February 1981) is a Spanish retired footballer who played as a central midfielder.
Formed at Barcelona, he spent most of his career with Rayo Vallecano, appearing in 219 competitive matches. Totalling both clubs, he amassed La Liga totals of 171 games and seven goals.
Born in Rábade, Province of Lugo, Galicia, Trashorras finished his football formation with FC Barcelona, playing one game with the first team on 6 October 2001, a 1–2 La Liga away loss against Deportivo de La Coruña where he came on as a second-half substitute for Alfonso Pérez. In the summer of 2003 he moved to Real Madrid, never graduating however from their reserves.
For 2005–06, Trashorras joined Segunda División side CD Numancia. He appeared very little during his tenure – less than one third of the games – and switched to UD Las Palmas also in the second level the following season, finally establishing himself in professional football.
In July 2008, Trashorras signed a five-year contract with Celta de Vigo in division two. An undisputed starter from the beginning he had his best season in 2009–10, scoring nine goals in 38 matches and helping the Galicians to the quarter-finals of the Copa del Rey, where they were ousted by eventual finalists Atlético Madrid (2–1 on aggregate, with the player netting in the first leg in Madrid in a 1–1 draw).
On 11 August 2011, after reaching an agreement to terminate his contract with Celta, Trashorras signed a contract with Rayo Vallecano, freshly promoted to the top tier. On 31 January 2018, after seven seasons as an undisputed starter and captain, the 37-year-old left the club.
On 29 August 2018, after several months of inactivity, Trashorras announced his retirement from professional football.
