Sheila Ann Dixon (born December 27, 1953) is an American politician (Politics of the United States). She was the forty-eighth Mayor of Baltimore, Maryland. When former Mayor Martin OMalley was sworn in as Governor on January 17, 2007, Dixon, a Democrat (Democratic Party (United States)), became mayor and served out the remaining year of OMalleys term. In November 2007, she was elected mayor by election. She is a former member of the Baltimore City Council, the first African-American female to serve as its president, and Baltimores first female mayor. She is also Baltimores third African-American mayor. Dixon endorsed Democrat Barack Obama for president in 2008.

On January 9, 2009, Dixon was indicted on twelve counts, including perjury, theft, and misconduct. The charges stem partly from incidents in which she allegedly misappropriated gift cards intended for the poor. On December 1, 2009, the jury returned a "guilty" verdict on one misdemeanor count of fraudulent misappropriation. On January 6, 2010 Dixon announced her resignation as Mayor as part of a plea agreement, effective February 4, 2010. She was succeeded by the Baltimore City Council President, Stephanie Rawlings-Blake on February 4, 2010.
