Roger Morris (19 April 1695 31 January 1749) was an English architect whose connection with Colen Campbell brought him to the attention of Henry Herbert, 9th Earl of Pembroke, with whom Morris collaborated on a long series of projects.Born in London, Morris received thorough practical training as a bricklayer, as he was described in 1724, when he built a house for himself on the Harley estate in Oxford Street, London, but by 1730, in a larger house he built for himself in Green Street, he was described in the rates as a 'gentleman'. On his own account he was successfully involved in speculative building in London, which may have supported his position in life.
