Muir's Winter Wren, Troglodytes troglodytes muiri , is a sub-species of Winter Wren that ranges coastally from southwest Oregon through Marin County, California.

The race was described by Amadeo M. Rea, who notes:

"The first bird named in honor of John Muir, whose life's work of conservation has helped protect the redwood habitat of this wren."
