Girton College is a constituent college of the University of Cambridge. The college was established in 1869 by Emily Davies and Barbara Bodichon as the first women's college at Cambridge. In 1948, it was granted full college status by the university, marking the official admittance of women to the university. In 1976, it was the first Cambridge women's college to become coeducational. Its sister college is Somerville College, one of the two Oxford colleges to first admit women.

The main college site is situated on the outskirts of Girton, about 2+1⁄2 miles (4 kilometres) northwest of the university town, and comprises 33 acres (13 hectares) of land. In a typical Victorian red-brick design, most was built by architect Alfred Waterhouse between 1872 and 1887.

Among Girton's notable alumni are Queen Margrethe II, former UK Supreme Court President Lady Hale, HuffPost co-founder Arianna Huffington, the comedian/author Sandi Toksvig, the comedian/broadcaster/GP Phil Hammond, the economist Joan Robinson, and the anthropologist Marilyn Strathern, who also held the position of Mistress from 1998 to 2009.
