The Black Horse is a Grade II listed public house at 65 Blackhorse Lane in South Mimms, Hertfordshire, England. It dates from the early 18th century and is of red brick with a tiled roof. Blackhorse Lane, which may be named after the pub, was the lane along which South Mimms developed. In 1847, a police station was built there, with married quarters added in 1908, but the surrounding areas was and remains rural.
