Llanllechid (Welsh: [ɬanˈɬɛχɪd]) is a village and community in Gwynedd, Wales. The village is near Bethesda, and the community had a population of 889 at the 2011 UK census and an area of 46 square kilometres (18 sq mi). The community also includes Tal-y-Bont near Bangor, Gwynedd and a large part of the Carneddau range so is therefore sparsely populated.

St Llechid is the patron saint of the village, where she founded the parish church and a holy well (now lost). The church closed in 2002.
