Michael S. Harrison (born 1968 or 1969) is an American former police officer who served as commissioner of the Baltimore Police Department (BPD) from 2019 to 2023. He was also the superintendent of the New Orleans Police Department (NOPD) from 2014 to 2019.

A graduate of the University of Phoenix and Loyola University New Orleans, Harrison joined the NOPD in 1991. He rose through the ranks of the department, ultimately becoming superintendent in August 2014, appointed by Mayor Mitch Landrieu to replace Ronal Serpas. During his time as superintendent, homicide and shooting rates fell, but theft significantly increased. He was reappointed as superintendent in May 2018. While he was recommended as a candidate for commissioner of the BPD, Harrison declined, wishing to remain with the NOPD. Despite this, Harrison ultimately agreed to join the BPD in January 2019 after leading candidate Joel Fitzgerald dropped out. Harrison officially became commissioner in March, a position he held until his resignation in June 2023, after which Richard Worley was appointed as acting commissioner. As commissioner, Harrison claimed decreases in homicides and shootings.
