Ernest "Ernie" Shoobridge Carr (1875 - 17 September 1956) was an early twentieth century member of the Australian House of Representatives.

Born in , Dubbo, New South Wales, Carr worked as a journalist and editor prior to gaining Australian Labor Party pre-selection for the Bathurst based electorate of Macquarie.

Carr won Macquarie at the 1906 federal election, aided by his opponent, the Postmaster General Sydney Smith, domiciliation outside the electorate, the nationwide growth in support for Labor and the strength of the union movement around the industrial city of Bathurst.

Carr comfortably held his seat over subsequent elections until his expulsion from the ALP in November 1916 following his support for conscription. He briefly served as an independent before joining the newly formed pro-conscription Nationalist Party of Australia in February 1917. In one of the closest polling results in Australian electoral history, Carr lost the 1917 election by nine votes.

Carr recovered from this result sufficiently to serve in the New South Wales Legislative Assembly as the Member for Cumberland from 1920-22. He later returned to journalism and became a newspaper proprietor until his death in Sydney.
