Edward Sholto Douglas-Pennant, 3rd Baron Penrhyn (10 June 1864 – 22 August 1927), was a British Conservative politician.
A member of the Douglas family headed by the Earl of Morton, Penrhyn was the son of George Douglas-Pennant, 2nd Baron Penrhyn, and his first wife Pamela Blanche, daughter of Sir Charles Rushout, 2nd Baronet.
He entered Parliament for Northamptonshire South in the 1895 general election, a seat he held until 1900, when he was replaced by his brother-in-law Edward FitzRoy.
Afterwards he served in the Buckinghamshire (Royal Bucks Hussars) Imperial Yeomanry as major[2] and later as lieutenant-colonel.
Penrhyn died in August 1927 at age 63, and was succeeded in the barony by his second and only surviving son Hugh.
