[Term] Supplemental Appropriations Bill [Link] N/A [Definition] 
Legislation appropriating funds after the regular annual appropriations bill for a federal department or agency has been enacted. A supplemental appropriations bill provides additional budget authority beyond original estimates for programs or activities, including new programs authorized after the enactment of the regular appropriations act. Such bills are often passed in response to emergency or otherwise urgent requirements which are too important to be postponed until passage of the next regular appropriations bill.
