Teh Chai Aan is a Malaysian politician who served as the Member of the Perlis State Executive Council (EXCO) in the Barisan Nasional (BN) state administration under former Menteri Besar Azlan Man from May 2018 to the collapse of the BN state administration in November 2022 as well as Member of the Perlis State Legislative Assembly (MLA) for Titi Tinggi from May 2018 to November 2022. He is a member of the Malaysian Chinese Association (MCA), a component party of the BN coalition. He is one of the only two MCA candidates elected in the 2018 state elections of all the states except Sarawak. He was also the sole Perlis EXCO Member and MLA of MCA and sole EXCO Member of the Chinese ethnicity.
On 13 June 2018, Teh was appointed as the Perlis State EXCO Member in Natural Resources, Environment, Biotechnology, Green Technology and Health by Menteri Besar Azlan.
On 22 November 2022, Teh lost his position after the BN state administration collapsed following the huge defeat of BN in the 2022 Perlis state election that wiped BN out of the assembly.
In the 2018 Perlis state election, Teh made his electoral debut after being nominated by BN to contest for the Titi Tinggi state seat. He won the seat and was elected into the Perlis State Legislative Assembly as the Titi Tinggi MLA after narrowly defeating Teh Seng Chuan of Pakatan Harapan (PH), Kamis Yub of Gagasan Sejahtera (GS) as well as the independent candidate Yaacob Man by a majority of only 142 votes.
In the 2022 Perlis state election, Teh was renominated by BN to defend the Titi Tinggi seat. He lost the seat and was not reelected as the Titi Tinggi MLA after losing to Izizam Ibrahim of Perikatan Nasional (PN) by a minority of 3,785 votes.
