The Church of St Martin in Elworthy, Somerset, England, is dedicated to St Martin of Tours. It dates from the 13th century and is recorded in the National Heritage List for England as a designated Grade II* listed building. Whilst the unbuttressed 2-stage crenellated tower is from the 13th century the porch and nave roof are from the late 15th century. The chancel was rebuilt in 1695 and again in 1846. It is built of red sandstone with Ham stone dressings and a slate roof. Within the church is an unusual alabaster font made with stone from a quarry near Watchet.
