Katherine Jane Chase Sprague (August 13, 1840 – July 31, 1899) was a Washington society hostess during the American Civil War. During the war, she married Rhode Island Governor William Sprague.

She was the daughter of Ohio politician Salmon P. Chase, who served as Treasury Secretary during President Abraham Lincoln's first administration and later Chief Justice of the United States. She was a strong supporter of her widowed father's presidential ambitions that, had he been successful, would have made her acting First Lady.
