Aditmari (Bengali: আদিতমারী) is the smallest upazila (sub-district) of Lalmonirhat District in Rangpur Division, Bangladesh.

Ibadat Khan, the Mughal faujdar of Ghoraghat, led an expedition against Koch Bihar in 1687, incorporating the region into the Bengal Subah once again.

[7] The status of Aditmari thana was upgraded to upazila (sub-district) on 7 November 1983, as part of the President of Bangladesh Hussain Muhammad Ershad's decentralisation programme.

Aditmari had a literacy rate (age 7 and over) of 45.06%, compared to the national average of 51.8%, and a sex ratio of 1003 females per 1000 males.

[11] Aditmari Upazila is divided into eight union parishads: Bhadai, Bhelabari, Durgapur, Kamalabari, Mohishkhocha, Palashi, Saptibari, and Sarpukur.

[14] Other than the Aditmari Central Graveyard, there are also Muslim cemeteries in Durgapur, Bhelabari, Kamlabari, Sarpukur, Saptibari, Bhadai, Palashi and Mahishkhocha.
