Halásztelek is a city in Pest County, Hungary. Halásztelek lies on the north part of Csepel Island, on the Danube.

The Romans, during their occupation, found Halásztelek dangerous because of the regular flooding of the Danube. It is likely that Attila the Hun started his attacks here against the Roman fortress which may have been at Százhalombatta. The occupying Hungarians from East Asia used Csepel Island as a summer retreat, and Szőlős, Háros and Tököl grew into settlements over time.

At the end of the 19th century the population of Halásztelek numbered no more than fifty.

The settlement was named after Ernő Warmann's sister and was called Herminamajor ("Hermina's field") or Herminatelep ("Hermina's land"). The next owner was Pál Sándor who grew melons. As agriculture became more developed, the population started to increase and in 1920 it reached 254 people. Not much later, the settlement had new owners in the Malonyay family, whose castle was famed for its balls. During the world economic crisis of the 1930s the family went bankrupt and workers and Bulgarian families started to buy parts of their estate (which is why signs at the city limits are in both Cyrillic and Latin alphabets). After these sales of the estate, the castle's value was greatly reduced, and István Füzessy became its owner. It is said that he lost the castle in a card game to Emil Stein. Stein planted peach orchards, and the land around the castle is still known as such, even though the land is now used for housing.
