The Burgumer Mar (officially known by its West Frisian name since March 15, 2007, previously called Bergumermeer in Dutch) is a lake of approximately 360 hectares located near the town of Burgum in the Dutch province of Friesland. Formed during the last ice age, the lake borders the villages of Jistrum, Eastermar, and Sumar in addition to Burgum itself. Its coordinates place it at roughly 53°11′N, 6°02′E in the northeastern part of Friesland.

A defining geographical feature is the Prinses Margriet Canal, which bisects the lake into a northern and southern section. Paddlers should be aware that this canal carries motorized vessel traffic, and the speed limit on the Burgumer Mar section of the Lits-Lauwersmeerroute is 9 km/h. The buoyed fairway runs toward the southern shore of the lake.

The lake is a recognized water sports area with multiple yacht harbours, making it a well-established destination for recreational boating. The village of Eastermar, accessible via De Lits waterway from the southern shore, offers marinas at Watersportbedrijf De Lits and De Komerk where paddlers can find moorings. Supplies and food are available in the village.

The Burgumer Mar forms part of the 15 km Burgumer Mar/De Leien kayak route, which starts from Sumar and is listed among the official kayak routes of Friesland. This route connects the lake with De Leien waterway, offering a structured day-trip option for paddlers. The lake also sits along the broader Lits-Lauwersmeerroute, a longer multi-waterway touring route through northeastern Friesland.

Paddlers should be mindful of slipping banks along connecting waterways, which can create shoals. The presence of motorized vessel traffic on the Prinses Margriet Canal crossing the lake is a practical consideration for those in smaller craft such as kayaks or canoes.
