Nielsen Racing is a British sports car racing team. Born in 2014, the outfit started off in Radicals before progressing to LMP3 in 2017 and LMP2 in 2020, making its debut at that year's 24 Hours of Le Mans. It has won titles in the Asian Le Mans Series and Le Mans Cup, and currently operates a two-car programme in the European Le Mans Series. In 2025 it expanded to single-seater racing by entering the Euroformula Open Championship, and in 2026 rebranded that operation as Northstar Racing.

The team was founded by former Greaves Motorsport engineer David 'Sven' Thompson in partnership with Nielsen Chemicals, a manufacturer of automotive cleaning products.
