The Berowra Creek, a watercourse that is part of the Hawkesbury-Nepean catchment, is located to the north of the Sydney central business district in the Hornsby Shire of New South Wales, Australia.

The Berowra Creek rises near Pennant Hills and flows generally north northeast before reaching its confluence with the Hawkesbury River about 7 kilometres (4.3 mi) west of Brooklyn,[1] and about 25 kilometres (16 mi) from the Tasman Sea.

[3] The creek is characterised by a drowned river valley estuary, consisting of steeply incised gorges with surrounding plateau areas.

It is fed by a number of small tributaries that drain the steep catchments adjacent to the waterway.

The tidal limit is at the Rocky Fall Rapids, some 23 kilometres (14 mi) from the creek's mouth.
