Kupon-e Sofla (Persian: كوپن سفلي) was a village in Rostam-e Seh Rural District of Sorna District, Rostam County, Fars province, Iran.
At the time of the 2006 National Census, the village's population was 227 in 48 households, when it was in the former Rostam District of Mamasani County.[2] The following census in 2011 counted 239 people in 57 households,[3] by which time the district had been separated from the county in the establishment of Rostam County. The rural district was transferred to the new Sorna District.[4]
After the census, the villages of Kupon-e Olya, Kupon-e Sofla, and Kupon-e Vosta were merged to form the city of Kupon.[4]
