Kalin Jay Lucas (born May 24, 1989) is an American professional basketball player for the Detroit Pistons of the National Basketball Association, on a two-way contract with the Grand Rapids Drive of the NBA G League.

As a freshman, Lucas immediately saw heavy playing time for the 2007–08 Spartans, averaging 25.1 minutes per game. His team-leading 13.5 points per game in the first two rounds of the NCAA Tournament were a major component of their Sweet Sixteen run. During his sophomore season, Lucas earned Big Ten Player of the Year honors, All-Big Ten first team selection, and was named Michigan State’s MVP, all while carrying the Spartans to the National Championship game against North Carolina. He led MSU in scoring (14.7 ppg), field goals made (173) and attempted (438), free throws made (172) and attempted (213), assists (4.6 apg) and minutes (31.9 mpg), while ranking second in steals (39).

He struggled to stay healthy the rest of the season, spraining his ankle a month before the Big Ten Tournament and eventually rupturing his Achilles tendon in the second round of the 2010 NCAA Tournament against Maryland. Lucas’ season was instantly put to an end, but the Spartans rallied, making their way to a second straight Final Four appearance.
