Julian Edward Gaillard (born August 13, 1970) is a former pitcher in Major League Baseball, playing for the Detroit Tigers and Tampa Bay Devil Rays between 1997 and 1999.

He took over the closing job that Korean pitcher Sun Dong-Yeol had left open after retiring, and led the league with 35 saves, appearing in the All-Star Game.

However, the Dragons began to use Akinori Otsuka as their closer, and he was put on waivers after complaining to the team about his lack of appearances.

He was picked up by the Yokohama BayStars, but was demoted to relief duty after Kazuhiro Sasaki returned as the team's closer in 2004.

He was one of the best closers in Japan in the early 2000s, ranking third among Chunichi Dragons players in saves, after Kaku Genji and Hitoki Iwase.
