The Indonesian Democratic Party of Struggle is a centre to centre-left secular-nationalist political party in Indonesia. Since 2014, it has been the ruling and largest party in the House of Representatives (DPR), having secured 110 seats in the last election. The party is led by Megawati Sukarnoputri, who served as the President of Indonesia from 2001 to 2004. It is also the former party of the current president, Joko Widodo (Jokowi).

The House of Representatives of the Republic of Indonesia is one of two elected chambers of the People's Consultative Assembly (MPR), the national legislature of Indonesia. It is considered the lower house, while the Regional Representative Council (DPD) serve as the upper house; while the Indonesian constitution does not explicitly mention the divide, the DPR enjoys more power, privilege, and prestige compared to the DPD.
