Jamie Cullum (born 20 August 1979) is an English pop and jazz-pop singer, songwriter, pianist, guitarist, and drummer.

Cullum was born at Romford Hospital in Essex, and educated at the independent fee-paying Grittleton House School and the sixth form at Sheldon School. Both are near Chippenham in Wiltshire. His mother, Yvonne, is a secretary of Anglo-Burmese origin, whose family settled in Wales after Burma's independence; his father, John Cullum, worked in finance. His paternal grandfather was a British Army officer, while his paternal grandmother was a Jewish refugee from Prussia who sang in Berlin nightclubs; Cullum has said that he sees her as his "cultural icon". He was brought up in Hullavington, Wiltshire but currently lives in North West London.
