1790–1792 United States House of Representatives elections in Massachusetts

Elections for the United States House of Representatives for the 2nd Congress were held in Massachusetts beginning October 4, 1790, with subsequent elections held in four districts due to a majority not being achieved on the first ballot.

Background
In the previous election, 6 Pro-Administration and 2 Anti-Administration Representatives had been elected. One representative, George Partridge (P) of the MA's 5th congressional district resigned August 14, 1790. His seat was vacant at the time of the 1790 elections, so that there were 5 Pro-Administration and 2 Anti-Administration incumbents, all of whom ran for re-election.

Three candidates ran in districts with different numbers from the previous election. It is not clear from the source used whether there was redistricting or if the districts had simply been renumbered.

Massachusetts law at the time required a majority for election. This occurred on the first ballot in the MA's 1st congressional district, MA's 2nd congressional district, MA's 3rd congressional district and MA's 4th congressional district districts. In the remaining four districts additional elections were required. In the MA's 5th congressional district and MA's 7th congressional district districts, a majority was achieved on the 2nd ballot. In the MA's 8th congressional district, a majority was achieved on the 4th ballot, while in the MA's 6th congressional district district, 9 ballots were required.

First Ballot
The first ballot was held on October 4, 1790. Four representatives, from the MA's 1st congressional district, MA's 2nd congressional district, MA's 3rd congressional district, and MA's 4th congressional district districts won on the first ballot.

Second ballot
The second ballot was held in the MA's 5th congressional district, MA's 6th congressional district, MA's 7th congressional district, and MA's 8th congressional district districts on November 26, 1790. A majority was achieved in the 5th and 7th districts on the second ballot
