Mieczysław Młynarski (born May 17, 1956 in Resko) is a retired Polish basketball player and a current head coach of the Górnik Wałbrzych. He was a regular member of the Poland national basketball team for nine years (1975–1984), including all matches of the Polish team during Summer Olympic tournament in Moscow, 1980. He was the best scorer in EuroBasket 1979 (26.6 per game) and 1981 (23.1), and still (as of May 2008) holds the national record of Poland in the "best score in one match" category (90 points, achieved in 1982 for Górnik Wałbrzych in the game against Pogoń Szczecin).
When his career ended he decided to stay in basketball. After retirement he took over the Górnik Wałbrzych juniors. In 2000 he achieved the Polish older juniors vice-championship (as the assistant coach) with Górnik. In 2007 he became the assistant coach of the Górnik Wałbrzych's seniors. After the coach's Andrzej Adamek resignation (in March 2009) he has become Górnik's head coach. Unfortunately, coach Młynarski has not been able to avoid his team's poor performances. In the 2008/2009 season Górnik finished at the last position in the PLK. The main reason why the team was relegated were deep financial issues (Górnik finished the season without any foreign players and some key Polish players e.g. Marcin Stefański)
