Mynediad Am Ddim is a popular Welsh folk-pop group formed in 1974 and currently comprising Alun "Sbardun" Huws, Emyr Huws Jones, and Emyr Wyn.

The six original members were students at University College, Aberystwyth : three vocalists, Emyr Wyn , Robin Evans and Mei Jones, and three instrumentalists, Iwan Roberts (guitar and mandolin), Graham Pritchard (violin, mandolin and piano) and Dewi Jones (French horn). The only intention at first was to compete in the 1974 Bangor Intercollegiate Eisteddfod, but following their success there they continued. In 1975 there was a key addition to the original six members, Emyr Huws Jones who had already made his name with Tebot Piws.
