Leo Pellervo Pusa (born 23 March 1947) is a Finnish athlete. He competed in the men's javelin throw at the 1972 Summer Olympics, but failed to register a result as he fouled all his three throws.[1]
His personal best throw was 82.48 metres (old javelin type), achieved in 1972.[1] He never became Finnish champion, with Hannu Siitonen taking all the national titles while Pusa was in his prime.[2]
