Taunton Unitarian Chapel is on Mary Street, Taunton, Somerset, England. It was built in the early 18th century as a Baptist chapel, but later adopted Unitarianism. The exterior was extensively renovated in the 19th century in an Italianate style. The chapel has been designated as a Grade II* listed building. In the early 21st century a range of structural and decorative restoration works were carried out on the building, which continues to serve the Taunton congregation, who meet for services twice a month at the chapel.
