Rhosgoch (Red Moor) is a small village in the north of the island of Anglesey, Wales, about 3.5 miles (5.6 km) to the south-west of Amlwch.
A short distance to the west of the village is the small lake Llyn Hafodol and a mile to the south is Anglesey's largest body of water the reservoir Llyn Alaw (Water Lily Lake).
The village once had a station on the Anglesey Central Railway. Although the tracks still exist no train has run on them since 1993.
