The Third Legislative Council of Hong Kong (Chinese: 香港第三屆立法會; pinyin: Xiānggǎng dì sān jiè lìfǎ huì) was the meeting of the legislative branch of the Hong Kong Special Administrative Region Government. The membership of the LegCo is based on the 2004 election. The term of the session was from 1 October 2004 to 30 September 2008, during the second half of the Tung Chee-hwa's administration until his resignation in 2005 and was replaced by Donald Tsang for the rest of the term, and also the beginning of the third term of Chief Executive after Tsang won in the 2007 Election. The Democratic Alliance for the Betterment of Hong Kong (DAB) became the largest party with 10 seats (not including the two DAB members who ran under the Hong Kong Federation of Trade Unions banner). Notable newcomers to the Legislative Council included Leung Kwok-hung, Alan Leong, Ronny Tong, Albert Cheng, and Jeffrey Lam.
