The A was a bus service operated by AC Transit in the San Francisco Bay Area. It was 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. The service was descendant from a Key System streetcar and ferry line that operated prior to the formation of AC Transit.
