DeWitt Clinton Cregier (June 1, 1829 - November 9, 1898) was an American engineer and politician.

The latter was a combination drinking fountain, fire hydrant, and watering basin for animals.

[4] As mayor, Cregier, alongside former Illinois Central Railroad president Edward Turner Jeffery and businessman Thomas Barbour Bryan, delivered the presentation for Chicago's successful bid to the fifteen member United States Senate committee that decided what location would be awarded the World's Columbian Exposition.

[6] However, he lost the election in a four-way race, featuring Carter Harrison Sr. as an independent Democrat, Hempstead Washburne as the Republican nominee, and Elmer Washburn as the "Citizens" nominee.

[7] In the 1893 Chicago mayoral election, Cregier ran as the nominee of the new "Citizens Party", but received little support.
