The 6-foot-6, 215-pound Rush has averaged 6.8 points, 1.8 rebounds and 1.1 assists in 314 games in five NBA seasons.
Last season with the Indiana Pacers, he averaged 8.3 points, a career-best 2.4 rebounds and 1.3 assists in 21.2 minutes per game and shot 39 percent from 3-point range.
"As we continue to build our team, we're fortunate that we were able to sign a player as talented as Kareem Rush," 76ers general manager Ed Stefanski said in a statement. "We feel his abilities on both ends of the floor and his range as a 3-point shooter will be assets to us this season."
Rush was the 20th overall pick in the 2002 draft by Toronto before his rights were traded to the Los Angeles Lakers. He also played for the Charlotte Bobcats.
