The Heegermeer, known in Frisian as the Hegemer Mar, is a lake in the province of Friesland in the Netherlands, situated adjacent to the village of Heeg. Its coordinates place it at approximately 52.957° N, 5.592° E, within the broader network of Frisian lakes in the Súdwest Fryslân municipality.

The lake contains several islands, including Rakkenpolle and Langehoekspolle, both of which offer the possibility of overnight stays, making them natural destinations for multi-day paddling trips. From the Heegermeer, paddlers can navigate onward to the Fluessen and subsequently to the Morra, providing options for extended routes through the connected waterway system.

A significant consideration for paddlers is the presence of a designated fast navigation area within the lake, marked by yellow buoys. Within this zone, motorized vessels are permitted to travel at higher speeds, which creates a meaningful hazard for non-motorized craft. Outside the buoyed fast navigation area, all boaters are required to adjust their speed to accommodate other water sports users, offering somewhat more predictable conditions for paddlers in those sections. Awareness of the buoy boundaries is therefore important when planning a route across the lake.

Swimming is permitted at beaches in Heeg and at Indijk, indicating some recreational infrastructure around the lake's shores.
