The Battle of Y Dalar Hir took place on 5 June 1648 in Caernarfonshire, North Wales, during the Second English Civil War. While little more than a skirmish, it had a significant effect on the local progress of the conflict.^[2]

Leading Welsh Royalist Sir John Owen of Clenennau mustered a group of 250-300 cavalry and foot in an attempt to raise North Wales in rebellion against Parliament; on 3 June he defeated local militia in a skirmish near Caernarfon and besieged Caernarfon Castle. Colonel George Twisleton, Parliamentarian governor of Denbigh, confronted Owen at Y Dalar Hir on the shore of the Menai Straits near Llandegai, where the Royalists were scattered and Owen captured, effectively ending the spread of the rebellion in North Wales.
