Map - Chhatak Upazila (Chhatak)

Chhatak (ছাতক) is an upazila of the Sunamganj District, located in the northeastern Sylhet Division of Bangladesh. It is named after its headquarters, the town of Chhatak, which is an important industrial centre in the division. Although it is currently part of the Sunamganj District, Chhatak is more closely related to Sylhet District for social, cultural, commercial and transport reasons. There are ongoing movements to establish a separate Chhatak District.

According to the majority of researchers including Dewan Mohammad Azraf, the area got its name from chhātā, the Bengali word for umbrella. It is said that upon the founding of a haat bazaar in such a rain-prone area, shopkeepers and shoppers would arrive with umbrellas and use umbrellas to prevent rain from falling on their fruits and crops. The area would be filled with umbrellas which later caused the market to be known as Chhātār Bazār (Umbrella's Market). Over time, it became corrupted into Chhātak Bazār. On the other hand, Monir Uddin Chowdhury asserted that Chhātak was actually corrupted from Chhatrāk, the word for an umbrella holder. He added that the area was first settled by a group of Chhatrāks who used to serve the local ruler.
