The Holden HR is an automobile that was produced by Holden in Australia from 1966 to 1968.

The Holden HR range was released in April 1966 In addition to a revised grille, the HR featured a reworked roofline and larger rear window (on the sedans), revised rear lights (on sedans and wagons) and changes to almost all exterior body panels. Other changes included revised ball joint front suspension, widened track, improved interior trim and woodgrain interior finish for the Premier models. Six months after the launch of the HR, all models were given a safety upgrade with the addition of front safety belts, windscreen washers, reversing lights, padded sun visors and a shatterproof interior rearview mirror
