Napoléon "Nap" Lajoie (English pronunciation: /ˈlæʒəweɪ/; September 5, 1874 – February 7, 1959), also known as Larry Lajoie, was an American Major League Baseball second baseman. He was born in Woonsocket, Rhode Island. In his career as a second baseman, he was considered one of the greatest players of the fledgling American League in the early 20th century, and the most serious of Ty Cobb's challengers.

Lajoie was elected to the Baseball Hall of Fame in 1937.

Lajoie started his career in the National League with the Philadelphia Phillies in 1896. In 1901, in response to a league-wide salary cap of $2,400 per year, he jumped to the crosstown Philadelphia Athletics, owned by former Phillies' part-owner Benjamin Shibe and managed by Connie Mack. Lajoie's batting average that year was .426. That same year Lajoie became the second Major Leaguer to be intentionally walked with the bases loaded after Abner Dalrymple in 1881. Only four other players have done it since: Del Bissonette in 1928, Bill Nicholson in 1944, Barry Bonds in 1998, and Josh Hamilton in 2008.
