The Shadow DN8 was used by the Shadow team during the 1976, 1977 and 1978 Formula One seasons. Driven by Alan Jones, it won the 1977 Austrian Grand Prix, Shadow's only Grand Prix victory.

The Shadow DN8 was conceptualised by Tony Southgate before he left the team to join Team Lotus. Dave Wass then completed the design work. It featured a low monocoque tub with hip radiators and an oil cooler positioned in the nose (but which would later be moved). Originally intended for the beginning of the 1976 season, a lack of funds following the withdrawal of major sponsor UOP the previous year meant the DN8 did not make its debut until late in the year, at the Dutch Grand Prix. Only one DN8 was produced for 1976, and it would not be until the third race of the following season that two DN8s were available for the drivers.

Southgate returned to the team in the summer of 1977, and this prompted development of the DN8; the chassis was slimmed down with the water and oil coolers reworked for the latter part of the season.
