Sir Edmund Probyn (1678 — 17 May 1742) was a British judge.

After 20 years of "the usual forensic drudgery",[1] Probyn secured appointment as a justice of the Brecon, Glamorgan, and Radnor circuit court in 1721, and became a Serjeant-at-Law on 27 January 1724, defending Thomas Parker, 1st Earl of Macclesfield at his trial for embezzlement.
[2] On 3 November 1726 he became a Justice of the King's Bench, succeeding Sir Littleton Powys,[3] and on 24 November 1740 became Chief Baron of the Exchequer,[4] succeeding Sir John Comyns.
[6] This he did, and later sat as a Member of Parliament for Wootton Bassett.
