Douglas Arlo Ose (born June 27, 1955) is an American businessman and politician who served as the U.S. representative for California's 3rd congressional district from 1999 to 2005.

[8] In an effort to complete construction of a border fence originally started in 1996, Ose, along with David Dreier, co-authored a bill that would grant the United States Secretary of Homeland Security authorization to ignore all laws deemed "necessary to ensure the expeditious construction of the barriers and roads under this section".

[9] According to The Sacramento Bee, during his congressional tenure, Ose appeared regularly in lists of the wealthiest members of Congress.

[13] In 2008, Ose ran in the primary election in California's 4th congressional district, a seat being left vacant by retiring Congressman John Doolittle.

[18] The Rothenberg Political Report rated the contest as a "Pure Toss-up";[19] and even eight days after the November 4 election, the race was still undecided, with Bera leading Ose by just 711 votes at the time with 19,000 ballots yet to be counted.

Ose hinted in 2017 that he was considering running for Governor of California in the 2018 election, telling the Los Angeles Times that he was "gravely concerned" about the state's future, elaborating "there's no other way to describe it – we've gone backwards.

While discussing his decision to not pursue the office at that time, Ose told Fox Business' Stuart Varney: "Cost of housing is out of control, K-12's failing, homeless everywhere, traffic gridlock, no jobs, it's just like...go down the checklist and they're 0 for life.

"[23] Ose then formed Rebuild California Foundation, a 501(c)(3) Tax-Exempt Educational Organization, to research and propose solutions for the top issues affecting the lives of everyday Californians.

[24] On March 16, 2021, Ose announced his intention to run for Governor of California in the recall election of Gavin Newsom.

[10] In 2011, when budget constraints forced the closure of Gibson Ranch Park in Rio Linda, Ose applied to run the facility as its private operator.
