Jimmy Levale Speigner (born September 24, 1980) is an American former Major League Baseball relief pitcher who played for the Washington Nationals.

A 14th-round pick by the Minnesota Twins in 2003, Speigner worked his way up the minor league chain, having a solid year in 2006 for the Double-A New Britain Rock Cats, and spent a short time with the Triple-A Rochester Red Wings.

In his June 2 start, however, while he gave up 6 runs on 6 hits in the first inning, he then retired 10 of the final 11 batters he faced.

On June 9, facing two-time Cy Young award winner Johan Santana, Speigner threw a gem, six innings, two hits, and one run, earning a 3-1 victory over the Minnesota Twins.
