Sir Percy Scott Worthington (31 January 1864 – 15 July 1939) was an English architect. He was born in Crumpsall, Manchester, the eldest son of the architect Thomas Worthington. He was educated at Clifton College, Bristol, and Corpus Christi College, Oxford, where he graduated in 1887, and he qualified as an architect in 1890. He subsequently worked as assistant to John Macvicar Anderson in London, attending the Royal Academy Schools and University College London, before returning to his father's office where he was made a partner in 1891. He continued the business after his father's death along with his much younger brother Hubert Worthington, who became a partner in 1913. Percy's son Thomas Scott Worthington later joined the partnership.
