Two ships of the Royal Australian Navy have borne the name Stalwart.

The first HMAS Stalwart (H-14) was an S class destroyer laid down by Swan Hunter and Wigham Richardson Limited of Wallsend-on-Tyne in April 1918, launched on 23 October 1918, completed in 1919, and transferred to the Royal Australian Navy at Devonport on 27 January 1920. HMAS Stalwart paid off to reserve on 1 December 1925 and was sold for scrap on 4 June 1937.
