The Pokok Sena District is a district and parliamentary constituency in Kedah, Malaysia. It is the 12th district of Kedah which was formerly a subdistrict of Kota Setar, about 20 km east of Alor Setar. The declaration of the 24,000ha district with a population of 50,000 was made by the Sultan of Kedah, Tuanku Abdul Halim Mu'adzam Shah in conjunction with his 81st birthday celebrations in January 2009 (also in commemorating the golden jubilee anniversary of his reign from 1958-2008). The district is divided into 6 sub-districts: Gajah Mati, Jabi, Tualang, Lesong, Bukit Lada, Derang and consists of 122 villages and 21 residential areas. The Pokok Sena district lies within the boundaries of the Alor Setar City Council (Majlis Bandaraya Alor Setar) local government area authority.

Pokok Sena is a Malay name for Angsana (Pterocarpus indicus), which is a common shade tree in Kedah. This tree was once usually found along the traditional river routes before the development of roads. Now most of the trees are found along roadsides and within office compounds.
