The Yeovil–Taunton line was a railway line in England, built by the Bristol and Exeter Railway (B&ER) to connect its main line with the market town of Yeovil in Somerset. It opened in 1853 using the broad gauge of 7 ft 1⁄4 in and was the first railway to serve Yeovil. It ran from a junction at Durston although in later years passenger trains on the line ran through to and from Taunton where better main and branch line connections could be made.

The Bristol and Exeter Railway (B&ER) was an English railway company formed to connect Bristol and Exeter. It was built on the broad gauge and its engineer was Isambard Kingdom Brunel. It opened in stages between 1841 and 1844. It was allied with the Great Western Railway (GWR), which built its main line between London and Bristol, and in time formed part of a through route between London and Cornwall.
