Thomas James Davis (August 13, 1952 – July 19, 2012) was an American comedian, writer, and author.

He attended The Blake School in Minneapolis, Minnesota, where he began his friendship and professional partnership with Al Franken.

In 1975, Davis got his big break as one of the original writers for Saturday Night Live where he and Franken also performed together.

Davis created the SNL sketches "Theodoric of York, Medieval Barber" (with Steve Martin), "Nick The Lounge Singer" (with Bill Murray), "The Continental" (with Christopher Walken), and "Coneheads" (with Dan Aykroyd and Jane Curtin).

He was treated at Mount Sinai Hospital, New York, where, on March 31, 2009, Dr. Eric Genden with minimally invasive robotic surgery, removed a tumor on Davis' right tonsil that had metastasized to an adjoining lymph node.
