Johannes "Jan" Lammers, (born 2 June 1956 in Zandvoort), is a racing driver and team principal from the Netherlands.
In 1979, Lammers made his debut in Formula One driving for Shadow and moved to ATS for 1980. He moved to Ensign mid-way through the season but rejoined ATS for four races in 1981. He joined Theodore for 1982. Ten years later he returned to Formula One for the final two races of the 1992 season.
He won the 24 Hours of Le Mans in 1988 and later participated in the race with his own team Racing for Holland. He was also the seatholder of the Dutch A1 Grand Prix team.
Lammers grew up as a kid washing cars at a sliding school in Zandvoort. As a 12-year-old he started to show customers how to slide safely, encouraged by sliding school owner and racing driver Rob Slotemaker who quickly recognized Lammers's talent. When he was 16 years old, he started his first race at the local racing track. In the following years he starred in Dutch touring car and Formula Ford races before moving up to European Formula 3 in 1977. He did not get good results with his Hawke and for his second season he joined Racing Team Holland run by Alan Docking. The other drivers of the team were fellow future Formula 1 driver Huub Rothengatter and later Indy 500 winner Arie Luyendijk. It was a successful move as Lammers won the 1978 European Formula 3 Championship after a close battle with Swede Anders Olofsson.
Jan Lammers (born 10 May 1995) is a Dutch professional football player who currently plays as a centre back for De Graafschap in the Dutch Eredivisie.

As a teenager Lammers trained in gymnastics and changed to athletics only after World War II. At the 1946 European Athletics Championships he was part of the Dutch 4×100 m team (with Jo Zwaan, Gabe Scholten and Chris van Osta) that finished in fourth place.
