Michael "Sheeny Mike" Kurtz (c. 1845 – November 24, 1904) was an American burglar and gang leader in New York City during the mid-to late 19th century. He was one of the co-founders of the Dutch Mob, along with Little Freddie and Johnny Irving, during the 1870s. Kurtz and the others controlled the area between Houston and 5th Streets for several years until the gang was driven out by "strong-arm squads" under Captain Anthony J. Allaire in 1876.
