Portland's festival calendar reflects the city's character — creative, community-driven, and deeply seasonal. Most of these events are community-produced, not corporate spectacles: the Rose Festival has run since 1907, and Saturday Market has been artist-run since 1974. Below is what's coming up next, then the full year by season — book early for peak weekends, because the city fills up fast.
