Caroline Mulroney Lapham (born June 11, 1974 in Montreal, Quebec) is the daughter of former Canadian Prime Minister Brian Mulroney and Mila Mulroney.

In 1991, she became the centre of controversy when Frank Magazine ran a satirical ad for a contest inviting young Tories to "deflower Caroline Mulroney". Many groups and commentators joined Brian Mulroney in denouncing the ad as an incitement to rape; however, the magazine took the stand that they were simply commenting on Mulroney's perceived habit of using his daughter as a political prop.

On September 16, 2000, Mulroney married Andrew Lapham, the son of Harper's editor Lewis H. Lapham. A singer at their wedding, Michael Bublé, attracted the notice of guests with connections in the music industry, and subsequently became a Canadian pop star in his own right.

On October 26, 2004, she gave birth to a boy, Lewis H. Lapham III, at New York City's Presbyterian Hospital.

She is currently associate director of the Stern School of Business at New York University.
