Topuzlu Dam (Turkish: Topuzlu Bent) is a historic dam located in Sarıyer district of Istanbul Province in Turkey.

Topuzlu Dam was built in 1750 by Ottoman Sultan Mahmud I (reigned 1730–1754). In 1786, its crest was raised about 3.40 m (11.2 ft) higher by Abdul Hamid I (reigned 1774–1789).[1] The dam is named "Topuzlu" meaning "bulged" due to a bulge-formed central part of the upstream wall side.

The dam is situated just north of Bahçeköy, Sarıyer inside the Bentler Nature Park, which is part of the Belgrad Forest.[2][3]

Topuzlu Dam impounds Eskibağlar Creek and has a catchment area of 0.92 km2 (0.36 sq mi). It is a solid gravity dam constructed in masonry. The dam is 14.00 m (45.93 ft) high from the thalweg and 80.65 m (264.6 ft) long at crest. The crest is 4.30 m (14.1 ft) and the base is 7.00 m (22.97 ft) wide. The dam has a reservoir capacity of 160,000 m3 (5,700,000 cu ft).
