Lewin's Mead Unitarian meeting house is a former Unitarian Chapel built in 1788–1791 on Lewin's Mead in Bristol, England.
Designed in the Neoclassical style by William Blackburn, the building was constructed on the site of a 1705 chapel; before that, the site had been a Franciscan Monastery.
The chapel was built by the Unitarians as a meeting house to hold 400 people, with stables and coach-house, a lecture room added in 1818, and schoolrooms in 1826. One notable minister, from 1817 to 1839, was Doctor Lant Carpenter, the father of social reformer Mary Carpenter. A Grade II* listed building since 1959, it was converted to offices in 1987 by Feilden Clegg architects, and housed the offices of a construction consultancy, Provelio. In January 2017 it was purchased by Emmanuel Bristol, for its city centre congregation.
Unitarians continue to meet in Bristol at their other places of worship, Frenchay Chapel and Brunswick Square.
