Primaries took place for four at-large seats and four district seats on the 13-seat Boston City Council on September 24, 2019, in Massachusetts. The council’s other five seats are also on the ballot this year, but they did not hold primaries because two or fewer candidates filed per seat. The primary winners advanced to the general election on November 5.
- At-large (four seats): All four at-large incumbents—Michael Flaherty, Althea Garrison, Annissa Essaibi George, and Michelle Wu—and challengers David Halbert, Julia Mejia, Erin Murphy, and Alejandra St. Guillen advanced from the 15-candidate primary. Eight candidates advanced from the primary because there are four at-large seats up for election, and two candidates advance per seat.
- District 5: Ricardo Arroyo and Maria Esdale Farrell advanced from the eight-candidate primary. Incumbent Tim McCarthy did not run for re-election.
- District 7: Incumbent Kim Janey and challenger Roy Owens defeated Valerie Hope Rust to advance from the primary.
- District 8: Kenzie Bok and Jennifer Nassour advanced from the five-candidate primary. Incumbent Josh Zakim did not run for re-election.
- District 9: Liz Breadon and Craig Cashman advanced from the seven-candidate primary. Incumbent Mark Ciommo did not run for re-election.
The five city council races not on the primary ballot were for Districts 1, 2, 3, 4, and 6. District 4 is scheduled to hold a contested general election between incumbent Andrea Campbell and challenger Jeff Durham in November. The incumbents in the other four seats—Lydia Edwards in District 1, Edward Flynn in District 2, Frank Baker in District 3, and Matt O’Malley in District 6—are all running unopposed for re-election.
