Luka Dumančić (born 27 October 1998) is a Croatian football player who plays for NK Nafta Lendava.
Dumančić started practicing football at GOŠK Kaštel Gomilica,[1] moving on to the youth system of Hajduk Split at the age of 11. Not retained by the club at the age of 19, he joined Italian Serie D club Albalonga for the 2017-2018 season.
On 13 July 2018, he signed a 2-year contract with Lecce, newly promoted to Serie B.[2]
After appearing on the bench for Lecce in two Coppa Italia games, on 12 August 2018 he was loaned to Serie C club Juve Stabia.[3] He made his professional Serie C debut for Juve Stabia on 24 November 2018 in a game against Rieti. He started the game and was substituted at half-time.[4] He finished the loan with 3 appearances, 2 of them as a starter.
As he returned to Lecce from loan, the club was promoted again. In the 2019–20 Serie A season, he appeared on the bench for Lecce on several occasions, but did not see any time on the field.[5]
On 7 January 2020, he was loaned to a Serie C club once again, this time to Gozzano.[6]
In late September 2022, following a season-long stint at the now-defunct Inter Zaprešić, Dumančić signed for NK Rudeš.[7]
