Oregon's best museums are surprisingly easy to visit for free if you time it right. In Portland, the newly expanded Portland Art Museum — now home to the Mark Rothko Pavilion — is free to everyone from 10 a.m. to 7 p.m. on the first Thursday of each month, and the Oregon Historical Society's museum is free every day for Multnomah County residents. Down the valley, the Hallie Ford Museum of Art in Salem is free every Tuesday, and Eugene's Jordan Schnitzer Museum of Art at the University of Oregon is free on the first Friday of each month (and pay-as-you-wish on Wednesday evenings). Even OMSI, the big science museum on the river, drops admission to $5 on about a dozen designated days a year. A handful of smaller art museums — the Schneider in Ashland, Bush Barn in Salem — are simply free all the time. Every entry below was checked against the museum's own admission page.
A few more budget moves: the Portland Art Museum also runs occasional 'Miller Family Community Free Days' beyond its first Thursdays — check its calendar. In Ashland, the ScienceWorks Hands-On Museum drops to $5 on the first Sunday of each month, and Eugene's Museum of Natural and Cultural History is a modest $7 (and just $1 for Oregon Trail/EBT cardholders). EBT cardholders get $1–5 admission widely across Oregon through Museums for All and the Oregon Trail Card program. Note that OMSI's $5 days are specific posted dates — roughly once a month but not always a Sunday (for example, one falls on a Tuesday in September), so check OMSI's '$5 Days' calendar before you go rather than assuming first Sunday.
Portland
Portland Art Museum
Regularly $27.50 adultsThe Portland Art Museum — the Northwest's oldest art museum, freshly expanded in 2025 with the Mark Rothko Pavilion connecting its two buildings — is free to all from 10 a.m. to 7 p.m. on the first Thursday of every month. Regular admission is $27.50 ($25.50 seniors/students, free for kids 17 and under). The museum also runs occasional 'Miller Family Community Free Days' on top of first Thursdays, so it's worth a look at the calendar before you pay.
🌐 Check current dates →Oregon Historical Society Museum
Regularly $14 adultsThe Oregon Historical Society's museum, right on the downtown Park Blocks, is free every day for Multnomah County residents — just bring proof of residency. For everyone else it's $14 ($12 seniors and students), and visitors 17 and under are always free. Highlights include the famous eight-story trompe-l'oeil 'Oregon History' murals on the building's exterior and the permanent 'Experience Oregon' exhibit. Open Monday–Saturday 10–5, Sunday 12–5.
🌐 Check current dates →OMSI (Oregon Museum of Science & Industry)
Regularly $22.50 adultsOMSI, the sprawling hands-on science museum on the east bank of the Willamette, isn't free — but on roughly a dozen designated '$5 Days' a year, general admission drops to just $5 per person (from $22.50), and the same $5 gets you the planetarium, the documentary theater, or a tour of the USS Blueback submarine. The catch: these are specific posted dates, not always the first Sunday, so check OMSI's '$5 Days' calendar first. Buy timed tickets online early — they draw crowds.
