The first USS Mayrant (DD-31) was a modified Paulding-class destroyer in the United States Navy during World War I.

Following her shakedown, Mayrant operated briefly off the New England coast before departing Newport, Rhode Island for a southerly cruise in late October.

Then, after completion of the 1915 winter exercises off Cuba, she steamed to the Brooklyn Navy Yard for overhaul prior to decommissioning on 20 May.

Departing Charleston on 16 July she sailed back to Philadelphia where she was decommissioned for a final time on 12 December 1919.

On 8 March, she was struck from the Naval Register; on 28 June, she was sold to M. Block & Company, Norfolk, Virginia for scrapping.
