A photo op (sometimes written as photo opp), short for photograph opportunity (photo opportunity), is an opportunity to take a memorable and effective photograph of a politician, a celebrity, or a notable event. Among amateur photographers, the term is used to refer to any opportunity to take good photos.

The term was coined by the administration of US President Richard Nixon. William Safire credited its coinage to Bruce Whelihan, an aide to Nixon Press Secretary Ron Ziegler. Ziegler would say Get 'em in for a picture, and Whelihan would dutifully announce to the White House press room, There will be a photo opportunity in the Oval Office.

The term has acquired a negative connotation, referring to a carefully planned pseudo-event, often masqueraded as news. It is associated with politicians who perform tasks such as planting trees, picking up litter, and visiting senior citizens, often during election cycles, with the intent of photographers catching the events on film, generating positive publicity.
