The 2007 Dacorum Borough Council election took place on 3 May 2007 to elect members of Dacorum Borough Council in Hertfordshire, England. This was on the same day as other local elections.
The whole council was up for election with boundary changes since the last election reducing the number of seats by 1 to 51.
The Conservative Party remained in overall control of the council after winning 44 of the 51 seats, partly attributing the "surprising" scale of the victory to national events, while the Liberal Democrats lost 2 seats but were pleased to become the official opposition.
Incumbent councillors standing for re-election are marked with an asterisk (*). Changes in seats do not take into account by-elections or defections.
