Al Bidda (Arabic: البدع) is a neighborhood of Doha, Qatar. It was previously the largest town in Qatar in the 19th century, before Doha, an offshoot of Al Bidda, grew in prominence. Al Bidda was incorporated as a district in the Doha municipality in the late 20th century. Qatar's Amiri Diwan (Presidential Office) has been based in Al Bidda since 1915, after being converted from an abandoned Ottoman fort.
