Neifi Pérez, Dominican-American baseball player
Neifi Neftali Pérez (; Spanish: [ˈnejfi]; born June 2, 1973) is a former Major League baseball player. He was a switch hitter who threw right-handed. During his career, he played with the Colorado Rockies, Kansas City Royals, San Francisco Giants, Chicago Cubs, and Detroit Tigers.

Pérez was originally signed by the Colorado Rockies in 1992. Frequently praised for his defensive skills, Pérez reached the major leagues in 1996 and become the Rockies' shortstop for good in 1997. Over the next three years, he scarcely missed a game and won a Gold Glove in 2000. During 2001, he was traded to the Kansas City Royals, where he also played in 2002. The trade proved to be unpopular with both teams, and Pérez joined the San Francisco Giants for 2003 and 2004. He lost his starting job during the 2004 season and was released during that year. Pérez then signed with the Chicago Cubs, whom he finished the season with and spent most of the next two years with. He was the Cubs' starting shortstop in 2005 but was used as a reserve player in 2006 before getting traded to the Detroit Tigers during the year. He finished his career in 2007 with the Tigers. As a Tiger, he turned a double play which saved Justin Verlander's no-hitter, but he also had a series of positive tests for amphetamines which effectively ended his career.
