The Tyrrell 015 was a Formula One car designed for Tyrrell Racing by Maurice Philippe for use in the 1986 season. The cars were powered by the turbocharged Renault EF15 V6 engine which was rated at 850 bhp (634 kW; 862 PS) in race trim. The 015 ran on Goodyear tyres and were driven by Martin Brundle in his third season with the team, and Philippe Streiff who joined from Ligier.

The 015 was a development of the team's first ever turbo car, the Tyrrell 014 which had first run the Renault turbo in Brundle's hands at the 1985 French Grand Prix. As the 015 was still unfinished at the start of the season, the team ran the 014 for the first three races of the season. The new car was finally ready for Monaco and proved to be somewhat reliable, if not the fastest car on the grid. Of the three teams which used versions of the turbocharged Renault V6 during the season, Tyrrell were usually slower than both Ligier and Lotus. This was usually explained by Lotus having a works contract to run the latest engines (as well as having the undisputed fastest driver in Grand Prix racing, Brundle's old British F3 rival Ayrton Senna), while the French Ligier team had been using the French engines since 1984. Tyrrell on the other hand, had a failed relationship with Renault during the early 1970s which prompted the factory to eventually form its own team in 1977, only had a contract to run customer engines which were usually the oldest, least powerful and economical of those on offer.
