Ahmad Samsuri bin Mokhtar (Jawi: أحمد سمسوري بن مختار; born 16 November 1970), better known as Dr. Sam, is a Malaysian politician, aerospace engineer and lecturer who has served as the 15th Menteri Besar of Terengganu and Member of the Terengganu State Legislative Assembly (MLA) for Ru Rendang since May 2018, Member of Parliament (MP) for Kemaman since December 2023 and group Chairman for Terengganu Incorporated (TI Group).

[8] When the Menteri Besar and 10 executive councillors (EXCO) was scheduled to be sworn-in before the Sultan of Terengganu, Sultan Mizan Zainal Abidin, PAS Terengganu State Commissioner Husain Awang declined to name the incoming Menteri Besar and EXCO members.

Earlier it was reported that PAS had submitted three names as candidates to be appointed as the Menteri Besar including Samsuri.

He won the seat and was elected the MP for Kemaman by defeating former Chief of Defence Forces Raja Mohamed Affandi of BN by a majority of 37,220 votes, which is a significantly increased majority, but lower turnout compared to the one garnered by Che Alias in the 2022 general election.

Ahmad Samsuri described his landslide victory as having paved the way for PN to the Putrajaya, which is the administrative capital of the nation.
