Massachusetts's 9th congressional district is located in eastern Massachusetts. It is represented by Democrat Bill Keating. With a Cook Partisan Voting Index rating of D+6, it is the least Democratic district in Massachusetts, a state with an all-Democratic congressional delegation.

Redistricting after the 2010 census eliminated Massachusetts's 10th congressional district; the 9th covers much of the old 10th's eastern portion. The district also added some Plymouth County communities from the old 4th district, and some Bristol County communities from the old 3rd and 4th districts. It eliminated a few easternmost Norfolk County communities and northernmost Plymouth County communities.

From 1963 to 2013, the 9th covered most of southern Boston, and in its latter years, it included many of Boston's southern suburbs. Most of that territory is now the 8th district.
