Dame Grace Hilda Cuthbertha Ross, known as Hilda Ross, was a New Zealand politician for the National Party and an activist.

The First National Government of New Zealand was the government of New Zealand from 1949 to 1957 formed by the National Party. It was a conservative government best remembered for its role in the 1951 waterfront dispute. It also began the repositioning of New Zealand in the cold war environment. Although New Zealand continued to assist Britain in situations such as the Malayan Emergency, it now became connected to Australia and the United States through the ANZUS agreement.
