# Londonderry (Assembly constituency)

54°55′19″N 6°57′11″W﻿ / ﻿54.922°N 6.953°W﻿ / 54.922; -6.953
Londonderry was a constituency used for the Northern Ireland Assembly.
The seat was first used for a Northern Ireland-only election for the Northern Ireland Assembly, 1973. Members were then elected from the constituency to the 1975 Constitutional Convention and the 1982 Assembly. After the Assembly dissolved in 1986, the constituency was not used again, its area being represented by parts of East Londonderry, Foyle and Mid Ulster.
It usually shared boundaries with the Londonderry UK Parliament constituency, however the boundaries of the two constituencies were slightly different from 1983 to 1986 as the Assembly boundaries had not caught up with Parliamentary boundary changes.
For further details of the history and boundaries of the constituency, see Londonderry (UK Parliament constituency).
