The 2018 United States House of Representatives elections in Massachusetts were held on November 6, 2018, electing the nine U.S. representatives from the Commonwealth of Massachusetts, one from each of the state's nine congressional districts. The elections coincided with the elections of other offices, including a gubernatorial election, other elections to the House of Representatives, elections to the United States Senate, and various state and local elections. The primary election for contested nominations was held on September 4, 2018.

On the night of the election, all nine races were declared in favor of the Democratic Party candidates. Seven seats went to incumbents seeking re-election: Richard Neal (1st District), Jim McGovern (2nd), Joseph Kennedy III (4th), Katherine Clark (5th), Seth Moulton (6th), Stephen F. Lynch (8th), and Bill Keating (9th). In the 7th District, Ayanna Pressley ran unopposed after defeating the incumbent in the primary election. In the 3rd District, where the incumbent did not seek re-election, Lori Trahan was declared the winner.

District 7

The 7th congressional district is located in eastern Massachusetts. It contains the northern three-quarters of the city of Boston, the city of Somerville and parts of the city of Cambridge. The district has a PVI of D+34. The incumbent was Democrat Mike Capuano, who has represented the district since 2013 and previously represented the 8th district from 1999 to 2013. He was re-elected unopposed with 99% of the vote in 2016.

In his bid for re-nomination by the Democratic Party, Capuano was defeated by Boston city councillor Ayanna Pressley.
The primary victory was a surprise, as the last poll before the election showed Capuano with a significant lead, 48% to 35%. Part of the reason the polls may have been inaccurate is a surge in the number of primary voters. 24% of District 7 voters in the 2018 primary had not voted in the five previous primaries, and that percentage was disproportionately of Hispanic and Asian ethnicities.
