Lillian West (October 11, 1855 – July 3, 1939), better known by the pen name Amy Leslie, was an American actress, opera singer, and drama critic.

In 1890, she began contributing to the Chicago Daily News, signing her stories as Amy Leslie, and became the drama critic for the paper.

After obtaining a divorce from Brown, Leslie was the mistress of Stephen Crane and lived with him in New York in a house at 121 West 27th Street.

Buck described her as "a small woman, plump, with keenly intelligent eyes, the most beautifully white teeth I have ever seen and a red, laughing mouth", adding that she was "always good-natured".
