Three Studies of Lucian Freud is a 1969 oil-on-canvas triptych by the Irish-born British painter Francis Bacon, depicting artist Lucian Freud. It was sold in November 2013 for US$142.4 million, which at the time was the highest price attained at auction for a work of art when not factoring in inflation. That record was surpassed in May 2015 by Version O of Picasso's Les Femmes d'Alger series.

A triptych is a work of art that is divided into three sections, or three carved panels that are hinged together and can be folded shut or displayed open. It is therefore a type of polyptych, the term for all multi-panel works. The middle panel is typically the largest and it is flanked by two smaller related works, although there are triptychs of equal-sized panels. The form can also be used for pendant jewelry.
