Lohagara (Bengali: লোহাগাড়া) is an upazila of Chattogram District in Chattogram Division, Bangladesh. Lohagara is situated between Chattogram and Cox's Bazar. It is one of the largest and most densely populated upazilas of Bangladesh.[1] It has headquarters in Lohagara.
In 1660, Mughal prince Shah Shuja took shelter in the Kingdom of Arakan to escape from Mir Jumla II. While heading to Arakan, he stayed in a beautiful hilly place (present-day Chunati) between Chittagong and Cox's Bazar for a few days. At the time of departure, he engraved an iron bar in that place as a sign. It is thought that because of engraving iron bar by Shah Shuja the area is called 'Lohagara' since 'Loha' means 'iron'.
