Eero Reino Lehtonen (April 21, 1898, Mikkeli – November 9, 1959) was a Finnish pentathlete. He won the Olympic gold at the 1920 and 1924 Summer Olympics. After pentathlon was removed from the Olympic programme for 1928, Lehtonen quit his career. His multi-event legacy still survived as Finnish decathletes, Paavo Yrjölä and Akilles Järvinen, took a double victory at the 1928 Summer Olympics. In 1984, Lehtonen got his own bronze statue at the sports park in Mikkeli, his home town .
