Thomas Patrick John Anson, 5th Earl of Lichfield (25 April 1939 – 11 November 2005) was an English photographer from the Anson family. He inherited the Earldom of Lichfield in 1960 from his paternal grandfather. In his professional practice he was known as Patrick Lichfield.
Thomas Patrick John Anson was born 25 April 1939. He was the only son of Lieutenant-Colonel Thomas William Arnold Anson, Viscount Anson (1913–1958), the eldest son and heir apparent of Thomas Edward Anson, 4th Earl of Lichfield (1883–1960). His mother was born Anne Bowes-Lyon (1917–1980), a niece of Queen Elizabeth the Queen Mother. His parents divorced in 1948, and his mother subsequently became Princess Anne of Denmark after her remarriage to Prince George Valdemar of Denmark in 1950. He had one sister, Elizabeth Georgiana (born 1941), who married Sir Geoffrey Adam Shakerley, 6th Baronet Shakerly.
Lichfield was educated at two boarding independent schools: at Wellesley House School, in the coastal town of Broadstairs in Kent, and at Harrow School, in Harrow-on-the-Hill in North West London, followed by the Royal Military Academy Sandhurst, in the small town of Sandhurst in Berkshire.
His father died in 1958, leaving Thomas to succeed as 5th Earl of Lichfield when his grandfather died in 1960.
