Willamette Valley Flood: Floods in the Willamette Valley of Oregon, United States, causes over US$500 million in property damage throughout the Pacific Northwest.

The Willamette Valley flood of 1996 was part of a larger series of floods in the Pacific Northwest of the United States which took place between late January and mid-February 1996. It was Oregon's largest flood event in terms of fatalities and monetary damage during the 1990s. The floods spread beyond Oregon's Willamette Valley, extending west to the Oregon Coast and east toward the Cascade Mountains. Significant flood damage also impacted the American states of Washington, Idaho (particularly the north of the state) and California. The floods were directly responsible for eight deaths in Oregon, as well as over US$500 million in property damage throughout the Pacific Northwest. Three thousand residents were displaced from their homes.
