Kentlyn Campsite, known as 'Kui' Kentlyn, is a Girl Guides NSW campsite located on the edge of the Georges River Basin, approximately 10 minutes from the centre of Campbelltown in New South Wales.

The site sits within bushland surroundings, reflecting the broader Kentlyn area's longstanding bush character — a quality preserved since the suburb was zoned for five-acre blocks in the 1920s and remained relatively undeveloped compared to neighbouring suburbs after World War II.

Peter Meadows Creek, a watercourse roughly 7. 5 kilometres long that flows northeast into the Georges River, runs through the local area. The campsite offers a quiet, natural setting within easy reach of suburban Campbelltown.
