Teffont Evias is a small village and former civil parish, now in the parish of Teffont, on the Nadder valley in the south of Wiltshire, England. Edric Holmes described the village as "most delightfully situated", and Maurice Hewlett included Teffont in his list of the half dozen most beautiful villages in England. The present buildings are mostly of local stone, and several are thatched.

The civil parish was combined in 1934 with neighbouring Teffont Magna to form a united Teffont parish.

Teffont Evias lies 3 miles (5 km) northeast of the large village of Tisbury and 6+1⁄2 miles (10 km) west of Wilton. The southern boundary of both the former Teffont Evias parish, and the modern Teffont parish, is the River Nadder. The village street follows the perennial stream, which rises at Spring Head at the north end of Teffont Magna, and flows some 2.5 km south to its debouchement into the River Nadder.

Purbeck limestone underlies almost all of the parish, with a ridge of Cretaceous Upper Greensand. Teffont Evias Quarry and Lane Cutting is protected as a geological Site of Special Scientific Interest, where fossils include some of the best Purbeck fish, with crocodile, turtle, and insect remains. The Chilmark Quarries extend under Teffont and some of the disused entrances are within Teffont parish.

In the 13th century, Teffont Evias's quarries of Purbeck limestone at the southern end of the former parish were the source of much of the freestone used in the building of Salisbury Cathedral.

A silver stater of the pre-Roman Durotriges tribe has been found in Teffont which may have been near the boundary of Durotrigian territory.

There is an extensive sacred site and settlement, with much Roman-period material but possibly started well before the Roman arrival, on the ridge to the west of the village.

At least two Roman cists were found in the quarry in Blackfurlong wood, some 200 metres west of the church. Their whereabouts are now unknown.
