The Florida-born driver joined the team at the start of 2023, his sophomore year in the IndyCar Series, and earned two victories at Long Beach and Nashville, driving the Andretti’s #27 Honda-powered entry.
He finished up the year with five additional top 10s, a pole and led 88 laps en route to 11th in the championship standings.
“I am thrilled to be able to continue with Andretti Global for years to come,” said Kirkwood.
“We have built something special within the team this year and I’m excited to see what we can do next season in the #27 AutoNation Honda.
"It’s fantastic that I will now have the opportunity to work with the same group – it’s a luxury I haven’t had the privilege of having since my karting days.
"Now we can put our heads down and fully focus on winning races and becoming a strong Championship contender.
"I have such a huge respect for this team and it will be an honor to continue to call myself an IndyCar driver for Andretti Global.”
