The Indonesian National Party was the name used by several nationalist political parties in Indonesia from 1927 until 1973. The first PNI was established by future President Sukarno. After independence, the new PNI supplied a number of prime ministers, and participated in the majority of cabinets in the 1950s and 1960s. The party was fused into the Indonesian Democratic Party in 1973. In the years following the reforms of the late 1990s, a number of parties claiming to be the continuation of previous PNIs stood in elections, but gained only a handful of seats.

Sukarno was an Indonesian statesman, orator, revolutionary, and nationalist who was the first president of Indonesia, serving from 1945 to 1967.
