Lucas Daniel Cavallini (born December 28, 1992) is a Canadian professional soccer player who plays as a forward for Liga MX club Puebla and the Canada national team.

Fénix, Cavallini emerged as the club's most prolific goal scorer in the Apertura of the 2014–15 Uruguayan Primera División season.

Cavallini was loaned to Liga MX side Puebla on August 31, 2017, becoming the first Canadian to play in Mexico's top tier since Isidro Sánchez Macip in 2010.

[12] In December 2019, Puebla and Major League Soccer side Vancouver Whitecaps FC agreed to a transfer, with Cavallini signing a three-year deal with the club ahead of the 2020 MLS season.

Cavallini's performance, along with the fact that he "plays in a different type of league (down in Uruguay)", according to head coach Stephen Hart, earned him his first call up to the senior roster to face Trinidad & Tobago in a friendly match on August 13, 2012.

Following that match, he declined a call-up from interim coach Colin Miller for the 2013 Gold Cup, citing personal reasons.

[25] Then coach Benito Floro gave an interview in October 2014 where he elaborated on Cavallini, saying that he had reached out to the player and had not heard back from him.

[29] In an interview regarding his return to the national team, Cavallini stated that he did not say he would never play for Les Rouges again, and that his comments were wrongly translated.

[30] Cavallini was named to the Canadian 40-man provisional team for the 2017 CONCACAF Gold Cup by Canada coach Octavio Zambrano on June 6, 2017.

[32] Cavallini scored his first goals for Canada on September 9, 2018, netting a brace in an 8–0 victory over the U.S. Virgin Islands in a CONCACAF Nations League qualifier.

[35] On March 29, 2021, Cavallini scored his second hat-trick with Canada, as a substitute, in an 11–0 win over Cayman Islands in the team's second 2022 World Cup qualifying match.
