Boston Express is a subsidiary bus company of Concord Coach Lines that operates between New Hampshire and Boston.

It serves locations between Logan Airport and southern New Hampshire, including Nashua and destinations along Interstate 93 as far north as Londonderry.

In 2017, the company began replacing these with Prevost X3-45 coaches, which, as of May 2024 make up all of the 25-bus fleet.

All buses are painted white with blue graphics.

As of October 2023, Boston Express no longer serves either Manchester or the Manchester-Boston Regional Airport, with service being cut back to the North Londonderry Transportation Center.
