# 2021–2022 Massachusetts legislature

The 192nd Massachusetts General Court was a meeting of the legislative branch of the state government of Massachusetts. It consisted of elected members of the Senate and House of Representatives. It first convened in Boston at the Massachusetts State House on January 6, 2021, during the governorship of Charlie Baker. The 192nd term ended in early 2023. Will Brownsberger, Michael Moran, and Dan Hunt oversaw decennial redistricting based on the 2020 census.
Also in 2021, legislators debated whether or not to increase public access to information about their own proceedings. Other notable discussion topics include progressive taxation, the gig economy, climate change, spending of federal aid, driver's licenses, animal welfare, and civil asset forfeiture.
