Ernest Robert Curtis (10 June 1907 – November 1992) was a Welsh professional footballer who played as an outside forward. Born in Cardiff, he joined hometown side Cardiff City in 1925, initially as an amateur before turning professional a year later. He made his senior debut in 1926 and helped the side win both the FA Cup and Welsh Cup in his first season. In the club's 1927 FA Cup victory, he became the youngest player to appear in a final in the competition's history as Cardiff defeated Arsenal, remaining the only team from outside England to win the trophy.
