Jair Francoise Jurrjens (pronounced /ˈdʒaɪ.ər ˈdʒɜrdʒɛnz/, JYE-ər JUR-jənz; born January 29, 1986 in Willemstad, Curaçao, in the Netherlands Antilles) is a starting pitcher for the Atlanta Braves. Jurrjens is represented by Scott Boras.

Jurrjens was signed as an undrafted free agent by the Detroit Tigers in 2003. In seven games during his 2003 campaign with the GCL Tigers, Jurrjens accumulated a 2–1 record with 20 strikeouts and just three walks. However, Jurrjens really broke out during his 2005 season with the West Michigan Whitecaps, the Tigers' single-A affiliate. In 26 games started, Jurrjens went 12–6 with 108 strikeouts and 36 walks. He continued to improve during the 2006 season, as a 5–0, 2.08 ERA start with the Whitecaps earned Jurrjens a promotion to the Erie SeaWolves, the Tigers' AA affiliate. In 12 games with the SeaWolves, Jurrjens went 4–3 with a 3.36 ERA.

Jurrjens began the 2007 season pitching for the SeaWolves. On August 15, the Tigers purchased Jurrjens' contract from the SeaWolves, adding him to their 40-man roster. Jurrjens made his major league debut on August 15, 2007, as a starting pitcher against the Cleveland Indians, making him the first pitcher from Curaçao to reach the major leagues. In that game, he gave up four earned runs in seven innings, taking the loss. He recorded his first major league win in his next start, also against the Indians, allowing only one run on one hit in 6⅔ innings pitched.
