The purple finch (Carpodacus purpureus) is a bird in the finch family, 'Fringillidae'.

Adults have a short forked brown tail and brown wings and are about 15 cm (5.9 in) in length and weigh 34 g (1.2 oz). Adult males are raspberry red on the head, breast, back and rump; their back is streaked. Adult females have light brown upperparts and white underparts with dark brown streaks throughout; they have a white line on the face above the eye.

Their breeding habitat is coniferous and mixed forest in Canada and the northeastern United States, as well as various wooded areas along the U.S. Pacific coast. They nest on a horizontal branch or in a fork of a tree. Birds from northern Canada migrate to the southern United States; other birds are permanent residents.

The purple finch population has declined sharply in the East due to the house finch. Most of the time, when these two species collide, the house finch outcompetes the purple finch. This bird has also been displaced from some habitat by the introduced house sparrow.
