The B was a bus service operated by AC Transit in the San Francisco Bay Area. It is one of the operator's many transbay routes, which are intended to provide riders a long-distance service across the San Francisco Bay between the East Bay and San Francisco. It specifically served Oakland's Grand Avenue corridor to the Grand Lake and Trestle Glen neighborhoods. The service was descendant of a Key System streetcar and ferry line that operated prior to the formation of AC Transit. The line was suspended in response to the COVID-19 pandemic.
