The Serbian Vojvodina (Serbian Voivodship, Serbian Duchy, Srpska Vojvodina, Српска Војводина) was a short-lived self-proclaimed Serbian autonomous region within the Austrian Empire during the 1848 Revolution, which existed until 1849 when it was transformed into the new (official) Austrian province named Voivodeship of Serbia and Banat of Temeschwar.

During the 1848 Revolution, the Hungarians demanded national rights and autonomy within the Austrian Empire. However, they did not recognize the national rights of other nationalities which lived in the Habsburg Kingdom of Hungary in that time.

Wishing to express their national individuality and confronted with new Hungarian authorities, Serbs declared the constitution of the Serbian Vojvodina (Serbian Duchy) at the May Assembly in Sremski Karlovci (May 13–15, 1848). The Serbian Vojvodina consisted of Srem, Bačka, Banat, and Baranja regions.

The Serbs also formed a political alliance with the Kingdom of Croatia "based on freedom and perfect equality". They also recognized the Romanian nationality. The metropolitan of Sremski Karlovci, Josif Rajačić, was elected for patriarch, while Stevan Šupljikac for the first duke (voivod). A National committee was formed as the new government of Serbian Vojvodina. Instead of the old feudal regime, a new reign was founded based on the national boards with the Head Serbian national board presiding.

Vojvodina, officially the Autonomous Province of Vojvodina (Serbian: Аутономна Покрајина Војводина / Autonomna Pokrajina Vojvodina [ʋǒjʋodina] ( listen) (see Name for other languages)), is an autonomous province of Serbia, located in the northern part of the country, in the Pannonian Plain of Central Europe. Its capital and largest city is Novi Sad.

Vojvodina has a population of about 2 million (approximately 27% of Serbia's total). It has a multi-ethnic and multi-cultural identity, with a number of mechanisms for the promotion of minority rights; there are more than 26 ethnic groups in the province, which has six official languages.

The name "Vojvodina" in Serbian language means a type of duchy – more specifically, a voivodeship. It derives from the word "vojvoda" (See: voivode) which stems from the Proto-Slavic language word "voevoda". Those words are etymologically connected with modern-day words "vojnik" (soldier) and "voditi" (to lead). Its original name (from 1848) was the "Serbian Voivodeship" (Srpska Vojvodina).
