The Attorney General of the State of Colorado is the chief legal officer for the U.S. State of Colorado and the head of the Colorado Department of Law, a principal department of the Colorado state government. It is an elected position with a four-year term, and follows the same schedule as election of the governor. The incumbent Colorado Attorney General is Democrat Phil Weiser, who was elected in November 2018 to a four-year term that began on January 8, 2019.

The Department of Law has seven sections: Appellate, Natural Resources and Environmental, Consumer Protection, State Services, Civil Litigation and Employment Law, Criminal Justice, Revenue & Utilities, and Business & Licensing.^[1]

From 1873 to 1877 the Attorney General position was filled by the U.S. Attorney due to lack of funding by the territorial government. In 1876 Colorado was admitted to the Union as a State.
