Pat Booth, Lady Lowe (24 April 1943 – 11 May 2009) was an English model, photographer and author of romantic fiction.

Raised in the East End of London by a boxer father and an ambitious mother, Booth posed for such photographers as Norman Parkinson and David Bailey in the 1960s. She opened two boutiques in London. She later became a photographer herself, taking pictures of such well-known figures as David Bowie and Bianca Jagger, as well as Queen Elizabeth II and the Queen Mother.

Her work has been displayed in the National Portrait Gallery and in The Sunday Times and Cosmopolitan. In the 1980s she turned her hand to writing racy and glitzy romance novels, partly inspired by her own glamorous lifestyle. She was published in both the U.S. and the UK.

She was, however, also a devout Roman Catholic and regular churchgoer. She provided assistance to women who became pregnant, but were unable to support a child.
