Onchan /ˈɔːŋkən/ is a village in the parish of Onchan on the Isle of Man. It is at the north end of Douglas Bay. Although administratively a village, it has the second largest population on the island, after Douglas, with which it forms a conurbation.
In Manx the name for the village is Kione Droghad meaning "bridge end".
In the 1890s a 5,000-year-old stone age axe was found in the Cassa Field by Onchan wetlands. In the Viking reign Onchan became part of Middle sheading. The name of the village is identified with St Connachan who was Bishop of Sodor and Man in 540 and the church named after him, Kirk Coonachan. An early name for the village is Manx: Kiondroghad which literally translated means "bridgehead". The earliest written record of Kiondroghad was in the 1643 Manorial Roll, when it was very small. The name Kiondroghad appeared on the 1841 census but not the subsequent one a decade later.
