Momai Tamuli (Assamese: মোমাই তামুলী বৰবৰুৱা ) was an able administrator and the commander-in-chief of the army in the Ahom kingdom of Assam. He was the first Borbarua, a new office created during the rule of the Ahom king Prataap Singha. He rose from a humble position as a bondsman to the office of the Borbaruah, which was a combined function of the Chief Executive Officer and those of the Lord Chief Justice. His sons Lachit Borphukan and Laluk Sola Borphukan played very significant roles in the History of Assam, as did his brother Baduli Phukan and sister Pakhori Gabhoru, an important Ahom queen. His granddaughter Ramani Gabhoru, daughter of Pakhori Gabhoru and Ahom King Swargadeo Jaydhawaj Singha, was married to Mughal prince Azam, son of Mughal Emperor Aurangazeb.
