This partial list of city nicknames in Colorado includes some of the sobriquets, pseudonyms, and slogans that identify, or have identified, the cities and towns of the U.S. state of Colorado. City nicknames can help in establishing a civic identity, helping outsiders recognize a community or attracting people to a community because of its nickname; promote civic pride; and build community unity. Nicknames and slogans that successfully create a new community "ideology or myth" are also believed to have economic value. Their economic value is difficult to measure, but there are anecdotal reports of cities that have achieved substantial economic benefits by "branding" themselves by adopting new slogans.
