Quintin Hogg (14 February 1845 – 17 January 1903) was an English philanthropist, remembered primarily as a benefactor of the Royal Polytechnic institution at Regent Street, London, now the University of Westminster.

[1] He showed strong religious convictions and held prayer meetings; he was also a prominent rifle volunteer.

As a senior partner in a firm of tea merchants, he modernised sugar production in Demerara at the plantation of his brother-in-law, the former slave owner Charles McGarel.

Hogg turned his energy to educational reform: in 1864 he founded York Place Ragged School.

With Arthur Fitzgerald Kinnaird (1847–1923, later 11th Baron Kinnaird) and Thomas Henry William Pelham[2] (1847–1916), he rented rooms in York Place (formerly Alley), off The Strand in central London, for a boys' school, initially a day school, later open in the evenings.

Hogg was an alderman of the first London County Council, encouraging the founding of other polytechnics, then called working men's (or mechanics') institutes.
