The Santa Clara Valley Transportation Authority, more commonly known simply as the Valley Transportation Authority (VTA), is a special district responsible for public transit services, congestion management, specific highway improvement projects, and countywide transportation planning for Santa Clara County, California. It serves San Jose, California, and the surrounding Silicon Valley. It is one of the governing parties for the Caltrain commuter rail line that serves the county. In 2023, the VTA's public transportation services had a combined ridership of 26,610,000, or about 87,500 per weekday as of the fourth quarter of 2023.

Ohlone/Chynoweth–Almaden was a short light rail route operated by Santa Clara Valley Transportation Authority (VTA) in southern San Jose, California, with three stops. Service into the Almaden Valley was also provided by VTA bus route 13, which also entirely duplicates the light rail service. VTA proposed to end service on the Ohlone/Chynoweth–Almaden line in late 2019, and officially announced plans to terminate service on the line and replace it with bus 64a on December 28, 2019.
