Alexandra Silverthorne (born 1980) is a Washington, D.C.-based artist and photographer. Her work focuses on spatial theory and exploration.
Silverthorne's first main works were from demonstrations in Washington and New York against the war in Iraq. In 2004, she was selected to be one of six American representatives at the 2004 World Conference Against A & H Bombs, a trip which resulted in a solo exhibit at the Dr. Martin Luther King, Jr. Library in Washington. Silverthorne is the recipient of grants from the D.C. Commission on the Arts and Humanities and the Puffin Foundation. A native of D.C., Silverthorne attended St. Mark's School in Southborough, Massachusetts and Connecticut College in New London, Connecticut where she majored in Government and minored in Art and Philosophy. She received her Master of Fine Arts in Studio Arts from the Maine College of Art in Portland, ME. Her photography can be found in the public collections of the John A.
