It is one of the largest upazilas of Bangladesh. It is a fertile valley between the Sitakunda Hills and the Hills of the Chittagong Hill Tracts. These two hill ranges become one at the northernmost point of the upazila and they widen apart as they proceed southwards. There is no particular geographical place in the upazila called Fatikchhari, rather the entire upazila takes its name from one small all-season rivulet known as Fatikchhari Khal that originates in the Sitakund Hills on the West and enters the Upazila at Bhujpur Union before joining the River Halda, the longest river in Fatikchhari Upazila that runs through the upazila along almost its entire length. Dhurung is its second longest river. There are some small rivers (khals) originating from the hills both on the eastern and western flanks, all being tributaries of the Halda flowing southwards to the sea. Among them are Gazaria, Fatikchhari, Baramasia, Mandakini, Balukhali etc. In between the two hill ranges, Fatikchhari consists of flat farmland annually affected by flash floods caused by heavy rainfall in the hilly catchment areas and the water being drained by several small rivers and the Halda.
It is surrounded by Tripura (India) to the north, Hathazari and Kawkhali Upazila (Rangamati District) to the south, Ramgarh, Manikchhari, Lakshmichhari, and Raozan Upazilas on the east, Mirsharai and Sitakunda Upazilas on the west.
According to the 1991 Bangladesh census, Fatikchhari had a population of 388,013, in 65,861 households. Males constituted 50.1% of the population, and females 49.9%. The population aged 18 or over was 182,250. Fatikchhari had an average literacy rate of 32% (7+ years), against the national average of 32.4% literate.
The population is a mix of Bengali Muslims and Hindus, Buddhists (all bearing the title Barua); Tripura, Chakma, Mogh (these tribal groups are gradually retreating into the CHTs and are becoming rare in the upazila); and Manipuri and Uria (mainly tea garden workers).
