Petrovaradin (Serbian Cyrillic: Петроварадин, pronounced [petroʋarǎdiːn]) is one of two city municipalities which constitute the city of Novi Sad. As of 2011, the urban area has 27,083 inhabitants, while the municipality has 33,865 people inhabitants. Lying across the river Danube from the main part of Novi Sad, it is built near the Petrovaradin Fortress, known as the "Gibraltar of the Danube".

Petrovaradin was founded by Celts, but its original name is not known. During Roman administration it was known as Cusum. After the Romans conquered the region from the Celtic tribe of Scordisci, they built the Cusum fortress where present Petrovaradin Fortress now stands. In addition, the town received its name from the Byzantines, who called it Petrikon or Petrikov (Πετρικον) and who presumably named it after Saint Peter.

In documents from 1237, the town was first mentioned under the name Peturwarod (Pétervárad), which was named after Hungarian lord Peter, son of Töre. Petrovaradin was known under the name Pétervárad during Hungarian administration, Varadin or Petervaradin during Ottoman administration, and Peterwardein during Habsburg administration.

Today, the municipality is known in Serbo-Croatian as Petrovaradin/Петроварадин, in Hungarian as Pétervárad, and in German as Peterwardein.
