Marghita (Romanian pronunciation: [marˈɡita]; Hungarian: Margitta [ˈmɒrɡittɒ]; German: Margarethen; Yiddish: מארגארעטין Margaretin) is a city in Bihor County, Romania.

The city borders the following communes: Viișoara and Abram to the east, Tăuteu to the south, Petreu and Buduslău to the west, and Sălacea and Pir to the north.

In the wake of the Second Vienna Award of August 30, 1940, the territory of Northern Transylvania (of which the town of Marghita was part) reverted to the Kingdom of Hungary.

In 1944, after German occupation, about 2,100 Jews of Marghita were sent to death, concentration, and labor camps as part of the Holocaust, of which only about 450 survived.

Towards the end of World War II, the town was taken back from Hungarian and German troops by Romanian and Soviet forces in October 1944, during the initial stages of the Battle of Debrecen.

The Marghita train station serves the Via Terra rail line connecting Oradea to Sărmășag, Sălaj County.
