Cégénydányádi Kastélypark Természetvédelmi Terület, Protected park in Szabolcs-Szatmár-Bereg County, Hungary.

Cégénydányádi Kastélypark is a protected landscape garden on the right bank of the Szamos at Cégénydányád, in Szabolcs-Szatmár-Bereg County. It was laid out in the 19th century in the English style on the site of floodplain forests, and its remaining old trees include a 25-metre London plane with a 690 cm trunk circumference, copper beeches, a ginkgo and a tulip tree. The grounds also hold the classicist manor built in 1833 for Zsigmond Kende.

The estate originated in 1833 when Zsigmond Kende built it in classical style and commissioned verses by Ferenc Kölcsey for its facade. The property later evolved into a botanical collection that eventually gained protected status.

The park's name links two villages, Czégény and Dányád, later merged into Cégénydányád, whose landowning families, the related Kende and Kölcsey clans, laid out the grounds. Zsigmond Kende chose the trees so that colours and forms harmonised and every season offered something to see; his grandson of the same name continued the planting, mainly with conifers. Kölcsey Ferenc's verses about the blond Szamos, inscribed on the manor, tie the place to Hungarian poetry.

The park lies on the south side of route 4136 in Cégénydányád, on the right bank of the Szamos. The manor reopened as a museum in 2015 after an 18-month reconstruction; the park itself has been under reconstruction since 1984. The giant plane trees stand behind the manor, while copper beeches greet visitors in the front garden.

The plane tree behind the manor is a London plane (Platanus × acerifolia), about 160 years old and 25 m tall, with a trunk girth near 7 m formed by three fused trunks; its long branches are propped with poles. Three more planes stand nearby, with trunk girths of 534, 449 and 487 cm.
