A by-election was held on 9 July 2010 in Dominica, to fill two seats in the House of Assembly that were declared vacant.
The contested seats were both won by significant margins by the incumbent candidates, who were members of the opposition United Workers' Party.
After two of the three UWP members, Edison James of Marigot and Hector John of Salisbury, did not attend three consecutive sessions of the Assembly, Speaker of the House Alix Boyd Knights declared their seats vacant, and a by-election was scheduled to fill the vacancies.
The Labour Party fielded the same candidates that ran unsuccessfully in the 2009 general election, Bentley Royer in Salisbury and Dayton Baptiste in Marigot.
Both James and John won the by-election by even greater margins than in the general election, leaving no change in the distribution of seats in the Assembly.
