2011 Bahraini parliamentary by-elections

Eighteen parliamentary by-elections were held in Bahrain in 2011 following the resignation of 18 MPs from the largest political party in parliament, Al Wefaq, in protest at governmental actions during the Bahraini uprising. Security forces closed Pearl Roundabout and attacked protestors in the village of Sanabis. The elections were held using a two-round system, with the first round on 24 September and the second on 1 October 2011 in the constituencies where no candidate had received a majority of the vote in the first round.
