The election was won by the incumbent Governor Apirak Kosayothin, placing him in his second consecutive four-year term in office, winning 45.93 percent of the vote.

Other candidates included Chuwit Kamolvisit, a former massage parlour businessman who also ran in the 2004 election, Prapas Chongsa-nguan, former governor of the Mass Rapid Transit Authority of Thailand and candidate for the People's Power Party, Kriengsak Chareonwongsak, an academic and professor in business administration, and Leena Jangjanja, a businesswoman and lawyer who ran in the previous election and the 2006 senate election.

The sixth elected governor of Bangkok, Apirak is the second to be elected to a second term, after Chamlong Srimuang, governor from 1985–1992, who was incidentally arrested at a polling station early on the election day, on charges of insurrection due to his role as leader of the People's Alliance for Democracy, a group which has staged protests and occupied Government House since August.
