Boston Book Festival 2026 — Copley Square

The Boston Book Festival is the city's biggest free literary event, anchored at Copley Square in mid-October with author readings, panel discussions, and a tent city of independent presses and literary nonprofits. Programming spans the Boston Public Library, Old South Church, Trinity Church, and the Square itself. T to Copley. 21+ adults: standard MA public-consumption framing applies — cannabis is for private; bookstores aren't the place.
