The House Wren, Troglodytes aëdon, is a small songbird of the wren family.

Their breeding habitat is semi-open areas from Canada to southernmost South America. The tropical forms from southern Mexico southwards are sometimes considered a separate species, the Southern House Wren, Troglodytes musculus. Birds on the Falkland Islands are now often considered to be an endemic species, Cobb's Wren, Troglodytes cobbi. North American birds migrate to the southern United States and Mexico.

This bird usually builds a large cup nest in various sorts of cavities, either natural or man-made, often using bird houses where they are available, and sometimes choosing unusual sites such as old shoes. The female incubates the clutch of three to six red-blotched cream-white eggs for 14-15 days, and the naked young take another 16-19 days to fledge.
