James Foster, senior was an architect active, particularly in Bristol, England, in the late-18th and early-19th centuries.
A pupil and apprentice of Thomas Paty, Foster is perhaps best remembered for his Georgian Gothic churches, particularly Clifton Church, in Bristol.
Foster was the father of James Foster, junior, who was also an architect (died 1836). In the early-19th century Foster worked in partnership with his son James in Bristol in the architectural firm Foster and Son based at No. 10 Orchard Street.
Foster died on 1 November 1823 at the home of another of his sons, Thomas (died 1849), who was also a Bristol-based architect.
