Colin Hargreaves Pearson, Baron Pearson, CBE, PC (28 July 1899 – 31 January 1980) was a Canadian-born English barrister and judge. Rising to sit as a judge in the House of Lords, he is best remembered for his unspectacular but efficient and courteous chairmanship of industrial inquiries and royal commissions. His 1978 report into civil liability and compensation for personal injury made proposals for state pensions for accident victims that were largely rejected by government at the time.
Born in Minnedosa, Manitoba, Canada, he was the youngest child of lawyer Ernest William Pearson (1861–1936) and Jessie née Borland (died 1948). When Colin was 7, the family moved to London and he was educated at St. Paul's School. He served in the Guards at the end of World War I before attending Balliol College, Oxford to study Classics (Literae Humaniores'). Taking up the law, he joined the Inner Temple and was called to the bar in 1924, becoming a student of Walter Monckton in the chambers of Frederick Temple Barrington-Ward KC. He later joined the chambers of Sir William Jowitt KC where he began to build up a substantial common law practice.
