Clarence Wells Halbert (August 31, 1874 – September 29, 1959) was an American lawyer and academic.
Returning to Minnesota, Halbert was admitted to practice in 1898 and joined a prominent local law firm managed by U.S.
Senator and Secretary of State Frank Kellogg, and Cordenio Severance.
Four years later, he entered into partnership with his brother Hugh, with whom he practiced for the rest of his career.
In 1900, along with Hiram F. Stevens, Ambrose Tighe, Moses Clapp, and Thomas D. O'Brien, Halbert founded the St. Paul College of Law, the first predecessor of William Mitchell College of Law.
