The Sharpe's Wren (Cinnycerthia olivascens), also known as the Sepia-brown Wren, is a species of bird in the Troglodytidae family. It was formerly considered a subspecies of Cinnycerthia peruana, but under the common name Sepia-brown Wren. As presently defined, Sharpe's Wren is found in dense undergrowth of humid Andean forests in Colombia, Ecuador, and northern Peru.
