Danas Pozniakas (19 October 1939 – 4 February 2005) was a Lithuanian amateur light-heavyweight boxer who won the European title in 1965, 1967 and 1969 and an Olympic gold medal in 1968.

Pozniakas was born in Poland as Dan Pozniak, and in the 1950s moved to Vilnius, Lithuania, where he took up boxing at age 13.

He won the Soviet title in 1962 and a European silver medal in 1963, but at the 1964 Olympic trials lost to Aleksei Kiselyov and was not selected.

He decisively won his first three bouts and received the Olympic gold by default, as his opponent Ion Monea had a broken nose from his previous fight and withdrew from the final.

[1][2] Pozniakas became the Honoured Master of Sports of the USSR in 1965 and was selected as the Lithuanian Sportsperson of the Year in 1968; in 1969 he was awarded the Order of the Red Banner of Labour.
