The slaty antwren (Myrmotherula schisticolor) is a small passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found from Mexico south through Central America, Colombia, Ecuador, Peru, and Venezuela.

The slaty antwren has three subspecies, the nominate M. s. schisticolor (Lawrence, 1865), M. s. sanctaemartae (Allen, JA, 1900), and M. s. interior (Chapman, 1914).
