Zwierzyniecki Forest (Polish: Las Zwierzyniecki) is a forest and natural reserve in Białystok, Poland.

The existing forest is a remanent of a primeval forest that existed on a much larger territory. From the early centuries of Bialystok's existence the development of the settlement the forest was related to it. Jan Klemens Branicki had part of the forest adapted for breeding animals and pheasants. During the reign of Tsars Alexander I and Nicholas I the forest was part of the palace property. In the second half of the 19th century the area of the forest began shrinking with the ongoing increased human activity and development. At the end of the century Trams in Bialystok began operating, passing in the forest as well. As a result, the remaining forest gained protection and its recreational merits became valued. Following the regaining of the independence, the newly formed Polish Army also wanted to keep this forest as a protection of a garrison with large transport junction. During World War I, an evangelical cemetery was established, where German soldiers who died in local hospitals were buried.

During the Second Polish Republic the forest became a popular destination for spending springy weekends, alongside with Dojlidy Ponds.

During the Second World War the forest suffered from the German and Soviet occupants who cut down many trees.

In the years 1946–1947, those executed by death sentence in the Central Prison of Białystok, and perhaps also those killed in UB raids, were buried in passages between existing graves and in drainage ditches surrounding the cemetery. Probably several to a dozen or so corpses were found there at that time. They were buried in wooden boxes - makeshift coffins, and sometimes without them. The entire Zwierzniecki Forest surrounding the cemetery was covered with a network of ditches and trenches, which could also be used to bury the remains of convicts. In the 1960s, the cemetery was razed to the ground, and the headquarters of Radio Białystok was built in its place. During construction, between regular cemetery burials, human remains buried irregularly were found. In 2002, an exhumation was carried out on the undeveloped part of the property of the former cemetery. No remains were found that could be considered remains of post-war burials. However, witnesses indicated that the graves they mentioned were located in the part of the cemetery that is currently occupied by the radio building.
