The 1999 Dacorum Borough Council election took place on 6 May 1999 to elect members to Dacorum Borough Council in Hertfordshire, England. This was on the same day as other local elections.
The whole council was up for election, with new boundary changes since the previous election and a reduction in overall councillors from 58 to 52. The Conservative Party made significant gains, winning exactly half of the total seats, and pushing the council into no overall control.
The election in Highfield & St Pauls ward was delayed until 3 June 1999 after the death of one of the original Conservative candidates.
Incumbent councillors standing for re-election are marked with an asterisk (*). Changes in seats do not take into account by-elections or defections.
