Madeline Stewart (born 2 August 2000) is a New Zealand racing driver competing in the Porsche Carrera Cup North America series in 2024.

The Stewart Sisters Racing duo competed on both sides of the Tasman Sea predominantly in Rotax based series before Madeline moved to KZ2 and Ashleigh to IAME X30.

She endured a tough start to the race falling a long way back before a late-race charge on a drying track saw her take the lead with one lap to go, winning by 10 seconds.

She later competed in two rounds of the Aussie Tin Tops, a series created to give people an opportunity to race during the pandemic.

Madeline has continued her journey with JDX Racing in 2024, making the move up into Porsche Carrera Cup North America.
