The Boston Book Festival (BBF) is an independent nonprofit group based in Cambridge, Massachusetts, and also the name of its main event. The nonprofit was founded in 2009 by Deborah Z Porter, and aims to "celebrate the power of words to stimulate, agitate, unite, delight, and inspire by holding year-round events culminating in an annual, free Festival that promotes a culture of reading and ideas and enhances the vibrancy of our city".

The annual book festival combines a street festival with an array of authors and other literary presenters from around the world. Daytime events at the BBF are free. In 2014, 32,000 people attended.^{[citation needed]}

Throughout the year, BBF hosts several literary events, several of which fall under their annual "Lounge Lit" series of literary outings, such as readings, cookbook author demos, and an annual literary pub trivia night. Since 2011, BBF has also hosted evening “kick-off” activities leading up to the Saturday festival.
