No, the state of Oregon in not on a peninsula nor is it a peninsula. It is a part of the main land of the North American continent.
Now there may be a city named Oregon on a peninsula, but the question was not specific on which Oregon, so this answer apples to the state of Oregon.
The Puget Sound, Olympic Peninsula, Oregon Coast, Eastern Washington agriculture region, Central Oregon recreation area are a few of them.
Oregon and California, the Rocky/Sierra Madre mountains, the whole Baja California peninsula are some examples.
Oregon is closer to northern Spain than to southern Spain, because it is at a higher latitude and because southern Spain is farther from the Atlantic than is northern Spain (Portugal occupies the Atlantic coast on the southern Iberian peninsula).
