Martin Jelínek was a Czech basketball player who won a league title with Mlékárna Kunín in the 1990s and played for the Czech national team, including qualifying for EuroBasket 1997. He was the younger brother of Josef Jelínek, the all-time top scorer in Czech basketball competitions. He died in October 2026, aged 55, after a serious illness.

Born in Kutná Hora, he made his name in Brno before his best years at Nový Jičín, where a knee injury effectively ended his top-level career before he was 30.
