Corris Uchaf (English: Upper Corris), locally known as Top Corris, is a village lying in the south of the Snowdonia National Park in Gwynedd, Wales. The extensive slate quarries that surround the village are its most prominent historical feature.
The village lies in the valley of the Afon Deri, and is threaded by the A487 road, a trunk road between Dolgellau and Machynlleth. To the south the Deri runs into the Afon Dulas in the neighbouring village of Corris.
Among the quarries that once thrived around the village are Abercwmeiddaw and Abercorris (also known as Cwmodyn) on the east bank of the river, and Gaewern and Braichgoch on the western slopes of the valley.
The narrow-gauge horse-drawn Upper Corris Tramway carried slate in waggons from the quarries to Maespoeth Junction, where they joined the main line of the narrow gauge Corris Railway which took them onward to Machynlleth.
The group consists of people from the village. The purpose of the group is to manage the funds from the sale of Eglwys Zinc or any other funds made available to the community for the benefit of the Corris Uchaf village and population.
