Irene Steer (10 August 1889 – 18 April 1977) was a Welsh freestyle swimmer. She was one of the three Welsh women who have won Olympic gold medals, the others being Nicole Cooke (cycling, 2008) and Jade Jones (taekwondo, 2012, 2016). In 1912, Steer won a gold medal in the 4 × 100 m relay and failed to reach the final of the individual 100 m race.
