Fulgazi (Bengali: ফুলগাজী), also spelt Phulgazi,[4] is an upazila of the Feni District, located in Bangladesh's Chittagong Division.

In circa 1553, a merchant from the Middle East known as Murad Khan settled in Chittagong, but due to devastating floods, later migrated to modern-day Sripur in Fulgazi.

The Maharaja of Tripura signed a peace treaty with Shamsher Gazi and his forces which included Nahar and Phulgazi.

The treaty mentioned that Nahar received 80 droṇ of revenue-free land, 14 zamindari mouzas and the title of Majumdar.

[6] During the Bangladesh Liberation War of 1971, Fulgazi was under Sector 2 commanded by Khaled Mosharraf and later ATM Haider.

On 10 June, the Mukti Bahini shot 50 Pakistani forces dead while they were crossing the Bandhua Bridge in Fulgazi.

[7] On 2 June 2002, Fulgazi thana was upgraded to a sub-district by gaining 6 union councils from Parshuram Upazila.

The 1998 floods caused heavy damages to Fulgazi's settlements, crops, livestock and other properties.

On 20 May 2014, Ekramul Haque, inaugural chairman of Fulgazi Upazila was shot and burnt alive at 45 years of age.

Since Fulgazi lies on a floodplain, it has water readily available for the irrigation of rice plantations and fish farming.
