Petr Sevcik (born 4 May 1994) is a professional Czech football player who currently plays for Slavia Prague and the Czech Republic national team. Having made his debut in the Czech First League in 2014, Sevcik has played most of his club football there, aside from the 2014–15 season, when he played in the second level.

At the end of the 2013–14 Czech First League season, Sevcik started his career at Sigma Olomouc and made his league debut for the club as a second half substitute in a 5–0 away loss at Sparta Prague. When Olomouc were subsequently relegated, he joined Opava on a half-season loan at the start of the 2014–15 Czech National Football League.

In the spring part of the 2015–16 Czech First League, Sevcik scored his first two league goals for Olomouc, but the season culminated in Olomouc's relegation for the second time in three seasons. After the end of the season, he was one of two players who left Olomouc to transfer to Slovan Liberec alongside teammate Jan Navratil, where Sevcik signed a three-year contract.

Sevcik played for Liberec for two and a half seasons. His performances there led to interest from Slavia Prague and Sparta Prague.

In January 2019, Sevcik moved to Slavia Prague. On 18 April 2019, Sevcik scored a brace in the away second leg of the Europa League quarter-finals against Chelsea.

In a UEFA Euro 2020 qualifying match against Kosovo on 14 November 2019, Sevcik debuted for the Czech senior squad, coming on on as a substitute for Lukas Masopust in the 76th minute. On 25 May 2021, he was selected in the Czech squad for the UEFA Euro 2020. On 12 June 2024, he was called up for the UEFA Euro 2024, replacing the injured Michal Sadilek.
