The spotted bamboowren (Psilorhamphus guttatus) is a species of suboscine passerine bird in the tapaculo family Rhinocryptidae.

It has at various times been placed in families Formicariidae (the antthrushes), Sylviidae ("typical" warblers), Thamnophilidae (antbirds), Troglodytidae (wrens), and Polioptilidae (gnatcatchers).

[2][3] The spotted bamboowren is genetically most closely related to the rusty-belted tapaculo (Liosceles thoracicus).

Its range extends from southeastern Minas Gerais and western Espírito Santo through Rio Grande do Sul in Brazil into Argentina's northern Misiones Province.

Its range is restricted to the southern Atlantic Forest, a biome that has undergone extensive clearing for agriculture and human settlement.
