Camp Curtin was a military training camp in Harrisburg, Pennsylvania, during the American Civil War.

When news of the bombardment and subsequent surrender of Fort Sumter in Charleston, South Carolina reached Washington, D.C. on April 14, 1861, President Abraham Lincoln called for 75,000 volunteers to join the Army to quell the rebellion of the Southern states. Across the North, eager recruits responded to calls from local governmental officials to join newly raised state regiments. Governor Andrew Curtin of Pennsylvania issued a proclamation asking for 13,000 able-bodied men to volunteer to help preserve the Union. Within three days, thousands of men had converged at Harrisburg to enlist, but they had no formal place to organize or drill. Dauphin County officials offered Governor Curtin the use of the County Agricultural Society on the northern outskirts of Harrisburg for these volunteers. Maj. Joseph F. Knipe officially opened the camp on April 18, 1861, and named it Camp Curtin in honor of the governor (the planned name had been Camp Union). From December 1861 to March 1862, the camp was commanded by Truman Seymour.

John Joseph Curtin (8 January 1885 – 5 July 1945), Australian politician, served as the 14th Prime Minister of Australia. Labor under Curtin formed a minority government in 1941 after the crossbench consisting of two independent MPs crossed the floor in the House of Representatives, bringing down the Coalition minority government of Robert Menzies which resulted from the 1940 election – aside from the formulative early parliaments, the only other hung parliament has resulted from the 2010 election. Curtin led federal Labor to its greatest win with two thirds of seats in the lower house and over 58 percent of the two-party preferred vote, and 55 percent of the primary vote and a majority of seats in the Senate at the 1943 election. Curtin died in 1945 and was succeeded by Ben Chifley, who retained government at the 1946 election with over 54 percent of the two-party vote and a continued Senate majority.

Curtin led Australia when the Australian mainland came under direct military threat during the Japanese advance in World War II. He is widely regarded as one of the country's greatest Prime Ministers. General Douglas MacArthur said that Curtin was "one of the greatest of the wartime statesmen". His Prime Ministerial predecessor and 1943 election Coalition leader, Arthur Fadden of the Country Party wrote: "I do not care who knows it but in my opinion there was no greater figure in Australian public life in my lifetime than Curtin."
