The lieutenant governor of Colorado is the second-highest-ranking member of the executive department of the Government of Colorado, United States, below the governor of Colorado.

The lieutenant governor of Colorado, who acts as governor of Colorado in the absence of the officeholder and succeeds to the governorship in case of vacancy, is elected on a partisan ticket.

After the 1966 general election, the Constitution of Colorado was amended to require the joint election of governor and lieutenant governor — candidates running as a ticket.

The current lieutenant governor is Dianne Primavera, a Democrat, who took office 8 January 2019.
