The Hokusō Line (北総線, Hokusō-sen^?) is a commuter rail line operated by the third-sector Hokusō Railway in Japan. It runs between Keisei-Takasago Station in Katsushika, Tokyo and Inba-Nihon-Idai Station in Inzai, Chiba. It is part of the primary Keisei route between central Tokyo and Narita International Airport through the Narita Sky Access Line. It uses the ATS Type 1 system.

Most trains are all-station "Local" services, but some limited-stop "Rapid" express trains have operated in morning and evening hours.

The first section of the line, from Komuro to Shin-Kamagaya, opened in March 1979, including a temporary connection to the Shin-Keisei Line at Kita-Hatsutomi. As other tracks were connected, it changed name to "Hokusō Kōdan Line" in April 1987. Over 17 years later, the railway properties of the HDC corporation transferred to Chiba New Town Railway (千葉ニュータウン鉄道, Chiba Nyūtaun Tetsudō^?), on July 1, 2004, and the whole line was renamed as the Hokusō Line.
