Jobágyi is a village in Nógrád County, Hungary, beside of the Zagyva river, under the Mátra mountain ranges.

King Charles I donated it to Master Demeter in 1326 after the death of the previous owner, the Zaar family.

It was the property of Miklós Szalánczi in 1344, voivode of Transylvania, who gained the right of ius gladii to the settlement from King Louis I.

On August 23 in 1831, due to the epidemic, there was a rebellion led by Pál Kaszaph, because the fake news spread that the wells had been poisoned.

The painter Géza Mészöly lived the settlement after 1882, who painted his picture "Birkanyáj" (The sheep flock) here.

The village council in 1951 requested to change the name of the settlement to Kossuthváros, Szabad-Mátra or Szabadságháza, but this was refused by the Ministry of the Interior.

1678 people live in the main inner area and 199 in Losonci Road, what is 0.9 km away from the village centre.
