Gustavo Adolfo Sánchez is a Colombian artistic swimmer. He won two gold medals in the solo free routine at the 2022 Artistic Swimming World Series as well as a bronze medal in the mixed duet technical routine. His gold medal in the solo free routine at the Paris stop of the 2022 World Series marked the first gold medal won by an artistic swimmer representing Colombia at a FINA Artistic Swimming World Series.

 Sánchez was born 31 August 2000 in Cali, Colombia. He dreams that one day the Olympic Games will include men in artistic swimming, which has been omitted from the Olympic program in both men-only and mixed gender duet events as least through the 2024 Summer Olympics. He was unaffected by the allowance of up to two men to compete in the team event (featuring eight team event members) at the 2024 Olympic Games as the International Olympic Committee also continued barring the entrance of men in the sport in solo and duet events. For his collegiate studies, he attends Javeriana University in Cali, where he studies visual communication design.
