Teofilo Yldefonzo (born 5 November 1903 - died June 19, 1942), (also spelled as Teofilo Yldefonso) known as the "Ilocano Shark" because of his aquatic skills, was a Filipino Olympian considered as the greatest swimmer of the Philippines, and among the greatest Filipino athletes in Philippine sports history. He is the first Filipino to win an Olympic medal and is the only Filipino Olympic multiple medalist.
Early life and swimming career
Yldefonzo was born in Piddig, Ilocos Norte and at a very young age, he honed his swimming skills in the rivers of his hometown. He started his swimming career at the age of 18 and has collected a total of 144 medals.
He won his first Olympic bronze medal in the 200 meter breastroke event of the swimming competitions at the 1928 Olympic Games in Amsterdam, Netherlands. His bronze medal-winning time was 2 minutes and 54.4 seconds. On the way to the final heat, Yldefonso broke the Olympic record in the semifinals by clocking at 2 minutes and 48.8 seconds.

Yldefonzo also served the Philippines as a soldier during the Second World War and perished in the Capas concentration camp as a prisoner by the Japanese imperial army. His remains were never found.
