Domingo Gómez-Acedo y Villanueva (6 June 1898 – 14 September 1980), also known as Txomin Acedo,[1][2] was a Spanish footballer who played primarily as a left-sided forward and sometimes as a left back.

[1] He is the youngest player and goalscorer in the history of Athletic, having made his debut – and scored – in the Campeonato Regional Norte on 18 October 1914, at the age of 16 years, four months and 12 days.

[6] Acedo is also the club's youngest player and scorer in the Copa del Rey having found the net on his debut in that competition on 25 April 1915, aged 16 years, 10 months and 19 days (neither Muniain nor Gainza played in the cup before turning 17).

[10][11] In the quarter-finals against Asturias on 13 November 1922, Acedo imprinted his name in the competition's history with an late equaliser in extra-time to level the scores at 2–2 and force a second extra period in which Asturas prevailed as 4–3 winners.

[12] Domingo Acedo's older brother Aquilino also played for Athletic Bilbao just prior to his younger sibling's debut; in his brief career he featured in the 1913 Cup final defeat to Racing Irun, and in the inaugural match at San Mamés stadium against the same opposition (now renamed Real Unión), before retiring through injury.
