Rodolfo Tan Cardoso (25 December 1937 – 21 August 2013) was a Filipino chess player. He was awarded the International Master title by FIDE in 1957, making him the first Asian to achieve it. Cardoso was born in Anda, Pangasinan. In 1956, he won Philippine Junior Championship. In 1957, he took fifth place in the fourth World Junior Championship in Toronto, which was won by William Lombardy with a perfect score of 11–0. In the same year, the Pepsi-Cola company sponsored an eight-game match in New York City between Cardoso, the 19-year-old Philippine junior champion, and Bobby Fischer, the 14-year-old U.S. junior champion. He was the only Filipino to beat Fischer. Fischer claimed the $325 victor's prize with a 6−2 score (+5 –1 =2).
