The Fairfax, later Ramsay-Fairfax, later Cameron-Ramsay-Fairfax-Lucy Baronetcy, of The Holmes in the County of Roxburgh, is a title in the Baronetage of the United Kingdom. It was created on 14 March 1836 for Henry Fairfax, in honour of his father, Vice-Admiral Sir William George Fairfax. The second Baronet assumed the additional surname of Ramsay in 1876, which was the maiden name of his maternal grandmother. The third Baronet assumed by Royal licence the additional surname of Lucy in 1892 after his marriage to Ada Christina Lucy, daughter and heiress of Henry Spencer Lucy. In 1921 he added by Royal licence the additional surname of Cameron. The sixth Baronet was the husband of Lucinda Lambton between 1986 and 1989.
Charlecote Park in the village of Charlecote in Warwickshire came into the Fairfax family through the marriage of the third Baronet to Ada Christina Lucy. The previous owners of Charlecote Park, the Lucy family, had become extinct in the male line. In the 20th century the family fell on harder times and they gave Charlecote Park to the National Trust.
The Lords Fairfax of Cameron are members of another branch of the Fairfax family.
