Mary Elizabeth Jenkins Surratt (1820 or May 1823 – July 7, 1865) was an American boarding house owner in Washington, D.C., in 1865 who was convicted of taking part in the conspiracy to assassinate U.S. President Abraham Lincoln. Sentenced to death, she was hanged and became the first woman executed by the US federal government. She maintained her innocence until her death, and the case against her was and is controversial. Surratt was the mother of John Surratt, who was later tried, but due to statute of limitations, was not convicted.
