Legislative Assembly elections were held in the Indian state of West Bengal in 2011 to elect the members of West Bengal Legislative Assembly as the term of the incumbent government was about to end. The election was held in six phases between 18 April and 10 May 2011 for all the 294 seats of the Assembly. In a high voltage election, a voter turnout of over 84% was recorded, the highest ever in the history of Bengal till then.

The All India Trinamool Congress-led United Progressive Alliance won an absolute majority of seats in the state in a historic win, marking the end of the 34-year rule of Left Front, the longest-serving democratically elected communist government in the world, a fact that was noted by international media. Notably, even the incumbent Chief Minister Buddhadeb Bhattacharjee lost his Jadavpur seat, which was considered an electoral bastion of the CPI(M), to Trinamool's Manish Gupta. Bhattacharjee became the second incumbent chief minister of the state to lose from his own seat, after Congress' Prafulla Chandra Sen's defeat in Arambagh to Ajoy Kumar Mukherjee of Bangla Congress in 1967.

Background This was the first legislative assembly election for the Vidhan Sabha since 2007 Nandigram anti land acquisition violence and the 2006 Singur anti land acquisition violence, led by opposition party chief Mamata Banerjee, caused deaths by police firing amidst protests.

The Left Front had governed West Bengal since 1977. The election also followed the defeat of the Left Front in the 2009 general election, as well as its relatively poor showing in Panchayat and municipal elections.

Delimitation

The 2011 election adopted re-drawn electoral constituencies based on the 2001 census, following the 2002 Delimitation Commission of India, whose recommendations were approved in February 2008.
