Hajdúszoboszló is a town in Hajdú-Bihar county, Hungary, 19 kilometres (12 miles) southwest of county seat Debrecen. It is the third largest town in Hajdú-Bihar county.

The town is located in the northeastern part of the Great Hungarian Plain. Three regions meet near the town: the Hajdúhát ridge to the north-north-east, the Hortobágy National Park (Puszta) to the north-north-west, and the Great Sárrêt and Berettyó region to the south. Szoboszló lies at an altitude of scarcely 100 to 110 metres (328-361 ft) above sea level and slopes slightly towards Hortobágy.

This is a landscape "where earth and sky meet", but not a monotonous plain, even for travellers accustomed to romantic mountains, since here and there the landscape is enlivened by the backwaters of the Tisza River with patches of reed, thousands of wild fowl, and inviting groves. The surroundings are the renowned puszta, the "glorious plain".

The water park includes water slides, an olympic-sized swimming pool, and a wave pool, while the spa features graded thermal pools, including a tepidarium and jacuzzi-type hot baths.
