Roger Henry Pocklington Senhouse (18 November 1899 – [1] 31 August 1970) was an English publisher and translator, and a peripheral member of the Bloomsbury Group of writers, intellectuals, and artists.

[2] Roger Henry Pockington Senhouse was the fourth and youngest son (there being also two daughters) of Humphrey Pocklington-Senhouse, JP, of Netherhall, Maryport, Cumberland (now Cumbria), and Ashby St Ledgers, near Rugby, Warwickshire, Colonel of the Westmorland and Cumberland Yeomanry Cavalry, and his wife Florence Catherine (died 1920), daughter of Turner A. Macan, of Carriff, County Armagh, of a gentry family of Drumcashel.

She married Joseph Pocklington, JP, of Barrow House- from a Nottinghamshire family recorded back to the reign of Henry VIII- who assumed his wife's surname.

[3] Senhouse attended both Eton College and Oxford University, where he was friends with Michael Llewelyn Davies, one of the boys upon whom Peter Pan was based.

The private letters of writer and Bloomsbury Group member Lytton Strachey reveal that Senhouse was his (last) lover, and with whom in the late ‘20s and early 1930s he had a sado-masochistic sexual relationship.
