The 2019 Newcastle 500 (commercially titled 2019 Coates Hire Newcastle 500) was a motor racing event for the Supercars Championship, held on the weekend of 22 to 24 November 2019.

It was the fifteenth and final event in the 2019 Supercars Championship and hosted Races 31 and 32 of the season.

[1] Scott McLaughlin entered the event as champion-elect with a 550-point margin over compatriot Shane van Gisbergen.

Prior to the event, Supercars announced a review of its social media policies after a number of drivers criticised the legitimacy of McLaughlin's championship online – the season had been marred by a parity dispute over the new Ford Mustang S550, the alleged use of team orders by DJR Team Penske at the Bathurst 1000, and McLaughlin's delayed disqualification from the Top 10 Shootout at Bathurst due to an engine irregularity.
