Plus 9 more recorded only rarely (fewer than 10 verified sightings). Counts from verified iNaturalist observations.
The Koch's Wolf Spider (Alopecosa kochi) is the most commonly recorded, with 179 verified observations, about 38% of all wolf spiders reported in Oregon. If you spot a wolf spider here, it is statistically most likely to be this one.
Oregon also hosts less common wolf spiders such as Rustic Wolf Spider, Pirate Otter Spider and Shoreline Wolf Spider, each recorded fewer than 100 times. These are the species worth a second look when you are out, since a sighting is more notable.
Not every one of these is originally from here. Rustic Wolf Spider and Sand Bear Spider are recorded by iNaturalist as introduced in Oregon rather than native, so they arrived with human help rather than on their own.
