Portrait photography or portraiture is a photography of a person or group of people that displays the expression, personality, and mood of the subject. Like other types of portraiture, the focus of the photograph is usually the person's face, although the entire body and the background may be included.

Portrait photographs have been made since virtually the invention of the camera. The relatively low cost of the daguerreotype in the middle of the 19th century led to a general rise in the popularity of portrait photography over painted portraiture. The style of these early works reflected the technical challenges associated with long exposure times and the painterly aesthetic of the time. Subjects were generally seated against plain backgrounds and lit with the soft light of an overhead window and whatever else could be reflected with mirrors. Advances in photographic equipment and techniques developed, and gave photographers the ability to capture images with shorter exposure times the making of portraits outside the studio.
