The Narrow Gauge Railway Museum (Welsh: Amgueddfa Rheilffyrdd Bach Cul) is a purpose-built museum dedicated to narrow-gauge railways situated at the station of the Talyllyn Railway in Tywyn, Gwynedd, Wales. The museum has a collection of more than 1,000 items from over eighty narrow-gauge railways in Wales, England, the Isle of Man, Ireland and Scotland. This includes six locomotives on display (and several others in store or at other sites); eleven wagons inside with a further eleven outside; a display showing the development of track work from early plateways to modern narrow-gauge tracks; several large signals along with single line working apparatus and documents; a growing collection of tickets and other documents, posters, notices, crockery and souvenirs; relics from vehicles scrapped long ago and the Awdry Study, re-created with the original furniture and fittings in memory of the Rev. Wilbert Awdry, an early volunteer on the Talyllyn Railway best known for his series of railway books such as "Thomas the Tank Engine."

In 1964 a charitable trust was formed to manage and develop the museum and this was replaced by the present Narrow Gauge Railway Museum Trust on 11 July 1994. The main activity of the trust takes place at the Talyllyn Railway Wharf station. Inside the museum interactive and static exhibits illustrate the diversity, individuality, technical ingenuity and charm of narrow-gauge railways. The fleet of historic wagons kept outside is operational and the original wagon weighbridge from 1865 has been restored and included in a redeveloped section of the Wharf yard including a purpose-built weighbridge hut. The first museum displays were in the old Gunpowder Store at Wharf station. Soon a walled yard, used for the storage of coal, was roofed over and an extension added in 1964. The building served well but had no insulation, was damp and cold in winter and hot and airless in summer making it difficult to conserve the collection. What was needed was a new
