The Economic Union Party (EUP, formally the Party for Economic Union with the United States) was a political party formed in the Dominion of Newfoundland on 20 March 1948, during the first referendum campaign on the future of the country. The British-appointed Commission of Government had administered the country since the financial collapse of 1934. The alternatives were "responsible government" (restoration of Newfoundland self-rule), or "Confederation" (joining Canada).
