Boudoir (/buːˈdwɑːr/; French: [bu.dwaʁ]) is a woman's private sitting room or salon in a furnished residence, usually between the dining room and the bedroom, but can also refer to a woman's private bedroom. The term derives from the French verb bouder (to sulk or pout) or adjective boudeur (sulking)—the room was originally a space to withdraw to.

Boudoir photography is a photographic style featuring intimate, sensual, romantic, and sometimes erotic images of its subjects in a photographic studio, bedroom or private dressing room environment,[1] primarily intended for the private enjoyment of the subjects and their romantic partners.[2] It is distinct from glamour and art nude photography in that it is usually more suggestive rather than explicit in its approach to nudity and sexuality, features subjects who do not regularly model, and produces images that are not intended to be seen by a wide audience, but rather to remain under the control of the subject.
