International Dark Sky Communities ~ a town, city, municipality, or other legally organized community that has shown exceptional dedication to the preservation of the night sky through the implementation and enforcement of quality lighting codes, dark sky education, and citizen support of dark skies.

An International Dark Sky Community excels in its efforts to achieve a community-wide lighting code, promote responsible lighting, dark sky stewardship, and exist as an example to surrounding communities on the possibilities available with the proper lighting. Each community shown below has gone above and beyond the requirements as stated in our International Dark Sky Community Guidelines.
