Hollwinkel Wood () is a woodland area that lies mainly on the territory of the borough of Preußisch Oldendorf in the North German county of Minden-Lübbecke. Within the wood the terrain is almost entirely level, lying between 50 and 52 metres above sea level (NN). A negligible piece of woodland in the south of only about 0.58 hectares belongs to the town of Lübbecke. With a wooded area of 47 hectares it is the largest stretch of woodland between the Wiehen Hills and the Mittelland Canal within the county of Minden-Lübbecke and also the largest wood in the borough of Preußisch Oldendorf north of the Wiehen, and Egge. In addition there is no woodland anywhere near this size within a radius of 4.5 km (i.e. 63 km² of the surrounding area). The wood measures around 1.3 km from northeast to southwest and, at its widest point, around from east to west. Hollwinkel Wood is bounded in the west by the Große Aue rive rand in the east by the boundary of the borough of Lübbecke. The Mehner Bach stream flows through the wood in the far northeast. In the northwest of the wood is a 0.25 hectare pond with a small island.
