The Oregon race pits Democrat Tina Kotek against Republican Christine Drazan and a strong independent candidate, Betsy Johnson, a former Democrat who is financially backed by Nike co-founder Phil Knight.
Biden will stump for Kotek just as recent public opinion polls suggest Drazan has pulled into the lead.
While some Democratic candidates around the country have distanced themselves from Biden, seeing him as a political liability, Kotek is hoping for both a political and fundraising boost.
Len Bergstein, a Portland-based public affairs consultant and political analyst, said that unlike in other states Biden could offer the Democrat a needed jolt in Oregon.
"The Democratic governor's candidate has got to pull in the kind of voter that normally votes for Joe Biden in a race like this, and energizes that turnout," Bergstein said.
