Katherine Hancock Ragsdale (born c. 1959) is an American Episcopal priest based in Massachusetts and former president and dean of Episcopal Divinity School. Before becoming dean she was director of Political Research Associates from May 2005 through June 2009.

She is an American progressive, and was a priest at St. David's Episcopal Church in Pepperell, part of the Episcopal Diocese of Massachusetts. Ragsdale has served for 17 years on the national board of the Religious Coalition for Reproductive Choice. She is also on the board of NARAL Pro-Choice America, The White House Project, the Progressive Religious Partnership, as well as the bi-national advisory board of the Center for the Prevention of Sexual and Domestic Violence. She presented to the United States Senate Committee on the Judiciary on behalf of NARAL Pro-Choice America and the Religious Coalition for Reproductive Choice in 2004.
She was named president and dean of Episcopal Divinity School on July 1, 2009. Her appointment was criticized by religious conservatives, including Anglicans, who have been particularly critical of her endorsement of the "blessing" of abortion.
