You may trademark a city name if it is used as a brand name for your products or services. For example, “NEW ORLEANS” is a registered trademark for a line of doors and window guards. Trademarking a city name does not mean that you own the city name, nor does it mean that you own the city. Trademarking that city’s name will prevent other companies from using the city’s name in association with a product or service similar to yours.
If you wish to trademark a city name, you should contact a trademark attorney to conduct a search of current trademarks. It is possible that someone already owns the trademark for your desired city name as it is very common for local businesses to include these city names in their promotional slogans or business names.
