Holzhausenpark, Park with a Baroque palace in Nordend-West, Frankfurt, Germany

Holzhausenpark is a 3.5-hectare park in Frankfurt's Nordend and Westend districts, the remnant of the Holzhausen Oed estate. At its centre stands the Holzhausenschlösschen, built 1727–29 to replace a moated castle; the surrounding Burgweiher was reduced to 0.2 hectares when the grounds were laid out as an English landscape garden around 1910.

The Holzhausen Oed estate, originally nearly 30 hectares, had a medieval moated castle at its centre; it was destroyed in the 1552 siege of Frankfurt and later rebuilt. From 1727 to 1729 the Holzhausenschlösschen replaced that castle in the pond. In the Gründerzeit much of the grounds was built over, and in 1912–13 the park became a public Volkspark after Adolph von Holzhausen, last male of his family, gave park and palace to the city.

The name of the park comes from the von Holzhausen family, one of the oldest patrician families in Frankfurt. Today, the grounds are used mostly by families and schoolchildren who come to walk or sit on the grass.

The park has several entrances and is easy to reach on foot or by public transport from central Frankfurt. A visit in spring or summer gives the best sense of the gardens, though the paths remain open year-round.

The Louis-seize wrought-iron gate at the Oeder Weg, over 200 metres from the Holzhausenschlösschen, is a remnant of the estate's former boundary; the chestnut avenue leading from it to the house dates from around 1910.
