Richard Walter Hubbell (November 8, 1840 – April 5, 1910) was an American lawyer, politician, and judge. He was a member of the Wisconsin State Assembly, representing Oconto County during the 1872 and 1873 sessions, and also served as county judge and district attorney. In the American Civil War, he served as a Union Army artillery officer. He was a son of Levi Hubbell—the first Wisconsin state official to be impeached.
