Sharpe, Paley and Austin are the surnames of architects who practised in Lancaster, Lancashire, England, between 1835 and 1946, working either alone or in partnership. The full names of the principals in their practice, which went under various names during its life, are Edmund Sharpe (1809–77); Edward Graham Paley (1823–95), who practised as E. G. Paley; Hubert James Austin (1841–1915); Henry Anderson Paley (1859–1946), son of Edward, usually known as Harry Paley; and, for a very brief period, Geoffrey Langshaw Austin (1884–1971), son of Hubert. The firm's commissions were mainly for buildings in Lancashire and what is now Cumbria, but also in Yorkshire, Cheshire, the West Midlands, North Wales, and Hertfordshire.

Edward Graham Paley, usually known as E. G. Paley, was an English architect who practised in Lancaster, Lancashire, in the second half of the 19th century. After leaving school in 1838, he went to Lancaster to become a pupil of Edmund Sharpe, and in 1845 he joined Sharpe as a partner. Sharpe retired from the practice in 1851, leaving Paley as the sole principal. In 1868, Hubert Austin joined him as a partner, and in 1886, Paley's son, Henry, also became a partner. This partnership continued until Paley's death in 1895.
