US Representative Niki Tsongas said Wednesday she will not seek another term in Congress.

“I feel it is a good time to go,’’ she told the Globe as she prepared to release a statement announcing her decision.

The Lowell Democrat was elected to the seat that was being vacated in 2007 by then-US representative Marty Meehan. She serves on the US House Armed Services Committee, where she has worked on sexual abuse and veterans issues.

“I am particularly very proud of the work we did challenging the sexual assault issues in the military,’’ she said.

Her late husband, Paul Tsongas, held the seat for two terms after his election in 1974. He later went to be a one-term Senator. He died in 1997 of cancer.
