Keller Auditorium, formerly known as the Portland Municipal Auditorium, the Portland Public Auditorium, and the Portland Civic Auditorium, is a performing arts center located on Clay Street in Downtown Portland, Oregon, United States. It is part of the Portland's Centers for the Arts. Opened in 1917, the venue first changed names in 1966, being renamed again in 2000 in honor of a $1.5 million renovation donation by Richard B. Keller. An extensive remodeling and modernization in 1967–68 effectively changed its original exterior appearance beyond recognition.
