1984 Welwyn Hatfield District Council election

The 1984 Welwyn Hatfield District Council election took place on 3 May 1984 to elect members of Welwyn Hatfield District Council in England. This was on the same day as other local elections. While the local elections across the country saw each party's share of the popular barely change Welwyn Hatfield was an exception to this, seeing the Conservatives lose nearly a tenth of the popular vote share. However, this did not translate into any seats changing hands for any party.
