Samuel W. McCall, American journalist and politician, 47th Governor of Massachusetts (d. 1923)
Samuel Walker McCall (February 28, 1851 – November 4, 1923) was a Republican lawyer, politician, and writer from Massachusetts. He was for twenty years (1893–1913) a member of the United States House of Representatives, and the 47th Governor of Massachusetts, serving three one-year terms (1916–19). He was a moderately progressive Republican who sought to counteract the influence of money in politics.

Born in Pennsylvania and educated at Dartmouth, he settled in Massachusetts, where he entered local politics on a progressive reform agenda. Elected to Congress, he continued his reform activities, and opposed annexation of the Philippines. He did not join the Progressive Party, but was insufficiently conservative for state party leaders, who denied him election to the United States Senate on two occasions. As governor, he directed the state's actions during World War I, and orchestrated early aid to Halifax, Nova Scotia following a devastating munitions ship explosion there in 1917.
