Daniele Bonera is an Italian professional footballer who plays as a defender for A.C. Milan in Serie A.

His UEFA Champions League debut was against Anderlecht, 17 October 2006, in which he received a red card after receiving a second yellow in the 47th minute for what, in the referees view, was petulantly kicking the ball away as Anderlecht waited to take a free kick. After struggling at right back, Bonera was moved to centre back after several defenders were injured and the acquisition of Massimo Oddo from S.S. Lazio in January, a natural right back. Bonera slotted in well at centre back, becoming one of Milan's better players.

Bonera struggled with a niggling injury in the second half of the 2008–09 season, joining Alessandro Nesta and Kakha Kaladze on the treatment table. In September 2009, he signed a contract extension which will last until 2013.

After a 10-month lay-off, Bonera made a successful 45minute comeback against Novara in the Coppa Italia on 13 January 2010. Because of Milan's great central defensive partnership of Alessandro Nesta and Thiago Silva, Bonera was deployed at his former position, right back. Bonera slotted in well at right back, playing much better in that position than when he first joined Milan. Because of this Bonera became Milan's starting right back but when Gianluca Zambrotta, Luca Antonini and Massimo Oddo all returned from injury, he lost his place as starting right back. However when Alessandro Nesta once again found himself on the treatment table, coach Leonardo chose Bonera to fill in for him.
