A general election was held on Monday, 29 November 1999 for members of the 10th Parliament of Malaysia. Voting took place in all 193 parliamentary constituencies of Malaysia, each electing one Member of Parliament to the Dewan Rakyat, the dominant house of Parliament. State elections also took place in 394 state constituencies in 11 out of 13 states of Malaysia (except Sabah and Sarawak) on the same day. This was the last election for Mahathir Mohamad as Prime Minister and Chairman of Barisan Nasional, until 2018. This was also the first election held in a single day nationwide.
6,631,094 out of 9,564,071 registered voters cast their vote in this election. Although Barisan Nasional maintained its majority in Parliament, its overall popular vote dropped to roughly 56%. The parliamentary results are as follows:
The opposition won a total of 113 state assembly seats, 98 of which went to the PAS, 11 to the DAP and 4 for Keadilan. In the states of Kelantan and Terengganu, the PAS won by a huge margin–41-2 against Barisan Nasional out of a total of 43 seats and 28-4 out of a total of 32 seats respectively, hence allowing them to form the state governments in these states. In addition, PAS also captured one-third of the state seats in Kedah, with the remaining two-thirds going to Barisan Nasional (UMNO won 16 seats, MCA 2 seats in Kedah).
The election results were seen as a great gain for PAS, who previously had no state seats in Kedah and capturing only one seat in Terengganu in the 1995 General Elections. Observers attributed this to the neglect by the Federal Administration in the states of Terengganu and Kelantan due to administration by different parties.
