Thomas Atkinson (1729–1798) was an English architect, best remembered for remodelling Bishopthorpe Palace in the Gothic Revival style.

Atkinson was born at York, the son of Thomas and Jane Marshall Atkinson. His father was a mason. He worked with his father and later developed an architectural practice based in York. The house that he built there for himself in about 1780 still stands at 20 St Andrewgate in the city centre.^[1] He was the leading Yorkshire-based architect of the second half of the 18th century.^[2]

Atkinson converted to Roman Catholicism; he received a number of commissions from the Yorkshire Catholic gentry. He was commissioned to design a new chapel for Bar Convent. The dome was concealed beneath a slate roof, so that it was hidden from view. Atkinson also built eight different escape routes into the Chapel, to ensure that if the building was stormed, the worshippers would be able to escape.^[3] In 1776, he produced designs for a planned development of the city of Sheffield which never came to pass.
