The station's pictogram depicts a heron, inspired by the theme of flight presented by Darlene Nguyen-Ely's sculpture Dragonfly. It was created by Christian French as part of the Stellar Connections series, another "STart" project, that projects destinations near stations onto fixed points within the pictogram. The points in Rainier Beach station's pictogram represent Rainier Beach High School, the Seattle Public Library's Rainier Beach branch, Beer Sheva Park, and Pritchard Island Beach.
