The Królewskie Wzgórze ('Royal hill'), known before 1945 as Królewska Góra in Polish and Königshöhe in German and now also known as Ślimak (Slug) and Sobótka (bonfire), is a 99.2-metre-high (325 ft) hill in Gdańsk in Poland.

It is located in the suburb of Wrzeszcz and was originally named after Frederick William III of Prussia (1770-1840).

The top of the hill was fortified around the middle of the 19th century; it was linked with Jäschkental Park.

It is located on Romualda Traugatta Street and is now a public park and not a recognised heritage site.

In 1925, the 'Danzig Charitable House-building Co-operative Homes" association built a neighbourhood of forty houses on the hill, some intended for one and some for four families.
