Bacon's 1963 work "Portrait of Henrietta Moraes" was snapped up by an unnamed telephone bidder at Christie's Post-War and Contemporary Art auction, which realised £80.6 in total.
The Bacon auction record is $86.3 million for his 1976 "Triptych" which was achieved at Sotheby's New York in May 2008.
The painting sold on Tuesday was described in the catalogue as "the most seductive painting ever realised by Francis Bacon". Bacon died in 1992 and is now regarded as one of the 20th century's most important artists.
