The Pacific Planetarium Association (PPA) is a non-profit organization with members mostly from planetariums in the western states of Alaska, California, Hawaii, Idaho, Nevada, Oregon, Washington.

Our mission is to facilitate communication and cooperation among members of the planetarium community to help them provide the very best services to their respective communities in science literacy, arts & humanities awareness, and understanding of our universe.
