The Chain Gate in Wells, Somerset, England, is an entrance gateway adjacent to the north side of Wells Cathedral, controlling access from St Andrew Street to the Cathedral Green within the Liberty of St Andrew.

[4] An undated sketch by Henry Edridge (1768–1821) shows the Chain Gate in the late 18th or early 19th century, with a much taller wall than exists today alongside the road approaching the gate.

[5] The Chain Gate is a two-storey building of Doulting stone ashlar with a Welsh slate roof.

The upper level provides a passageway between the Chapter House of the cathedral and Vicars' Close.

There is a slight bend within the passageway as the entrance to the cathedral, via the approach staircase past the Chapter House, and that in Vicars Hall were not exactly opposite each other.
