Sealand[1] is a community in Flintshire and electoral ward, north-east Wales, on the edge of the Wirral peninsula.

[7] The local Society was wound up in 1961,[8] after which the leases of the homes passed to Hawarden Rural District Council.

It is on the A548 road, near the Chester dormitory communities of Blacon and Saughall and is a popular place of residence for people from both sides of the Welsh/English border.

Welsh-medium primary education is available three miles away at Ysgol Croes Atti's Shotton site (opened in 2014) whilst Welsh-medium secondary education is available nine miles away in Mold at the long established Ysgol Maes Garmon.

Though not about the community, the 1981 song "Sealand" by Wirral band Orchestral Manoeuvres in the Dark took its title from the RAF base there.
