Barty has represented Australia in the Hopman Cup twice. She made her first appearance at the event in 2013 where she competed alongside Bernard Tomic after Dellacqua withdrew before the tournament due to a foot injury. The Australians finished their round-robin group in second place behind Serbia. They defeated Germany and Italy in their first and last ties, but lost to Serbia in a close tie that was decided by a match tiebreak in the mixed doubles. During the tie against Italy, Barty won a lopsided singles match against former French Open champion and world No. 35 Francesca Schiavone in just 55 minutes, the biggest singles win of her career at the time.
