The Stoney Littleton Long Barrow (also known as the Bath Tumulus and the Wellow Tumulus) is a Neolithic chambered tomb with multiple burial chambers, located near the village of Wellow in the English county of Somerset. It is an example of the Severn-Cotswold tomb and was scheduled as an ancient monument in 1882. It was one of the initial monuments included when the Ancient Monuments Protection Act 1882 became law.
