Lakshmipur-3 is a constituency represented in the Jatiya Sangsad (National Parliament) of Bangladesh.
The constituency encompasses Lakshmipur Sadar except for nine union parishads North Hamsadi, South Hamsadi, Dalal Bazar, Char Ruhita, Parbati Nagar, Shakchar, Tumchar, Char Ramanimohan, and Bakshipur integrating the remaining areas under a single administrative and electoral boundary.
After the death of the previous MP of this constituency A. K. M. Shahjahan Kamal, new by-elections were taken on 5 November 2023. However, the Bangladesh Election Commission has decided to cancel the results of the election after a video went viral online of a former Bangladesh Chhatra League leader (Awami League's student wing) is seen stamping the "boat" symbol of Awami League in 43 ballot papers in 57 seconds.
A.K.M. Shahjahan Kamal from Bangladesh Awami League won uncontested.
