Auditor Suzanne Bump will not seek reelection, creating a rare opening for one of the state's six constitutional offices.
Bump said she is still dedicated to the job, but she believes it it time for others to bring new ideas to the office.
"I want to create the opportunity for another leader who shares my commitment to making government work better and building the public trust to pursue this mission," Bump said in the statement. "The public deserves to choose from a wide field, and this announcement will help make that possible."
Bump's career on Beacon Hill dates back nearly four decades. In addition to working as a lobbyist, she was a member of the House and served as labor secretary during Gov. Deval Patrick's administration.
In 2010, Bump edged Republican Mary Connaughton to succeed longtime Auditor Joe DeNucci. She coasted to easier wins in 2014 against Patricia St. Aubin and in 2018 against Helen Brady.
