The Sea Cliff Bridge, together with the adjoining Lawrence Hargrave Drive Bridge, are two road bridges that carry the scenic Lawrence Hargrave Drive across the rockface on the Illawarra escarpment, located in the northern Illawarra region of New South Wales, Australia. The balanced cantilever and incremental launching girder bridges link the coastal villages of Coalcliff and Clifton and carry two lanes of traffic, and a pedestrian walkway.

The Sea Cliff Bridge was named by Makenzie Russell, who at the time was an eleven-year-old student, following a naming competition opened to local primary school students. The Lawrence Hargrave Drive Bridge and the Lawrence Hargrave Drive are named in honour of Lawrence Hargrave, an Australian engineer, explorer, astronomer, inventor and aeronautical pioneer.
