Dhumketu (Bengali: ধূমকেতু dhūmkētu, "comet") was a bi-weekly magazine edited by Kazi Nazrul Islam which was first published on 11 August 1922.

While Nazrul was in jail, Biren Sen Gupta and Amaresh Kanji Lal edited the magazine.

[1] In the Puja Issue of the Dhumketu magazine published on 22 September 1922, Nazrul wrote an anti-British political poem[2] named Anandamoyeer Agamane (English:The Advent of the Delightful Mother).

On 23 January 1923, Nazrul was arrested by the police of the Bengal Presidency on charge of sedition for his statements in the poem.

While in jail, Nazrul and his co-prisoners started an indefinite fast as a protest against the Bengal Police administration's atrocities and oppression that lasted for 39 days.
