The Roslyn Packer Theatre Walsh Bay is a theatre in Sydney, New South Wales, Australia.

The theatre is on Hickson Road at Walsh Bay, 150 metres (490 ft) west of The Wharf Theatre, opposite Pier 6/7 on Walsh Bay.

Originally named as the Sydney Theatre, the theatre was renamed in March 2015 in honour of Roslyn Packer AC, the widow of Kerry Packer.

James Packer and family made a philanthropic gift to the Sydney Theatre Company in advance of the renaming.
