Gvozd (Serbian Cyrillic: Гвозд) is a municipality in central Croatia, Sisak-Moslavina County. Its seat is located in Vrginmost (Вргинмост), which was renamed to Gvozd from 1996–2012. It is an underdeveloped municipality which is statistically classified as the First Category Area of Special State Concern by the Government of Croatia.

Croatian is the official first language. Serbian language with its Cyrillic alphabet is the officially recognised second language. In Cyrillic, Vrginmost is known as Вргинмост and (between 1996 and 2012) Gvozd as Гвозд.

In 1097, the last native Croatian King Petar Snačić was killed here during the Battle of Gvozd Mountain, which led to the mountain being renamed Petrova Gora. It was ruled by Ottoman Empire between 1536 and 1691 as part of Bosnia Eyalet.

The village of Vrginmost has existed since 1688, when it was part of the Military Region. According to the census of 1850, Gvozd had 30 houses and 341 inhabitants, and according to the census of 1921, 622 households.

In the summer of 1941, the villages of then District of Vrginmost suffered heavy loss of civilian life with several hundred ethnic Serb men and boys perishing in the Glina massacre on 3 August 1941. Majority of the victims of the August massacre in Glina were from the villages of Blatuša, Podgorje, Crevarska Strana, Slavsko Polje, Brnjavac, Pješčanica, Gornja Čemernica, Donja Čemernica, Bukovica and Batinova Kosa.

The Ostrožin Rulebook (Croatian: Ostrožinski pravilnik) was adopted on 14 December 1941 in the village of Ostrožin. Predating the Foča Regulations by more than a month, the Ostrožin Rulebook was the first legal act which regulated the new national authority in the liberated territories during the National Liberation War of Yugoslavia.

In 1942, Andrija Artuković ordered the killing of the entire population of Vrginmost and its surrounding villages in 1942, according to the charges laid against him in his deportation hearings in the United States.

The town was officially known as Gvozd between 1996 and 23 October 2012. In 2012, its original name of Vrginmost was restored amid political controversy.

During the Croatian War of Independence, Vrginmost was a part of the unrecognized breakaway Republic of Serbian Krajina. It was retaken by the Croatian army during Operation Storm.

The municipality consists of 19 settlements:
