Samuel Mráz (born 13 May 1997) is a Slovak professional footballer who plays as a forward for Polish club Motor Lublin.

Mráz started his football career at hometown club ŠK Malacky, before first moving to TJ Záhoran Kostolište and later to the youth academy of Senica.

[4] He scored his first goal for Senica that season in a league match 28 November 2014; a regional derby against Spartak Trnava, which ended in a 1–1 draw.

[9] Mostly a substitute through the fall of the 2019–20 season, Mráz made two subsequent starts during regular forward Kamil Wilczek's two-match suspension.

[13] On 13 August 2020, Mráz joined Polish Ekstraklasa club Zagłębie Lubin on a season-long loan with an option to buy.

[17] On 9 August 2021, after his loan with Zagłębie Lubin ended, Mráz moved to Serie A club Spezia on a permanent deal, signing a three-year contract.

Slovan had signed him to increase the internal competition ahead of Europa Conference League group stage as well as domestic duties and to allow Mráz to regain the form, which earned his initial transfer to Serie A.

[30] On 12 February 2024, Mráz returned to Poland to join I liga side Motor Lublin, signing a deal until the end of the season, with an option for another year.

[31] He scored six goals in sixteen appearances, as Motor went on to win the 2023–24 I liga promotion play-offs and returned to the Ekstraklasa after 32 years of absence.

However, Mráz was also an alternate for friendly games against the Netherlands, Morocco, Denmark and Slovakia's first UEFA Nations League match against Ukraine.
