Logan Evans Costa (born 1 April 2001) is a professional footballer who plays as a centre-back for La Liga club Villarreal. Born in France, he represents the Cape Verde national team.

Costa is a former French youth international, having represented them at U16 and U17 level, before switching to play for Cape Verde in 2022.

Costa was born in Saint-Denis, Île-de-France, to a Cape Verdean family.

Having started to play football in Argenteuil, Val-d'Oise, Costa joined the youth academy of Reims in 2016.

A player in Reims's Championnat National 2 reserve starting in the 2018–19 season, Costa captained the side during the following campaign. With a few first-team appearances in Ligue 1 games, he was loaned to Championnat National side Le Mans for the 2020–21 season.

With Le Mans newly relegated from Ligue 2, he was one of the standout players in the team, and a revelation of the Championnat National, starting and playing the entirety of 26 games, as the club only narrowly missed the promotion play-offs.

After this promising loan spell, Costa was offered a contract extension by Reims, but chose to look elsewhere in search of more game time. With one year left on his contract, several clubs from France, Italy and Germany were interested in signing him. He was eventually transferred to Toulouse in August 2021.

Costa made his professional debut for Toulouse on 13 November 2021, starting and playing every minute of a penalty shoot-out victory over Libourne in the Coupe de France, in which he helped his team keep a clean sheet. Starting the season behind Rasmus Nicolaisen, Bafodé Diakité and Anthony Rouault, with a team aiming for promotion, Costa first only made bench appearances in Ligue 2. However, he established himself as a regular starter in the Coupe de France, even scoring his first goal against Trélissac.
