What Car? is a British monthly automobile magazine and website, currently edited by Steve Huntingford and published by Haymarket Consumer Media. Other team members include deputy editor Darren Moss and test editors Will Nightingale, Neil Winn, Lawrence Cheung, Dan Jones and Max Adams. The used car editors are Mark Pearson and Oliver Young. The consumer editor is Claire Evans. The editorial director is Jim Holder.

First published in November 1973, What Car? is intended primarily as a magazine for car buyers rather than dedicated enthusiasts. In addition to first drives and group tests of the latest models, it contains an extensive buyer's guide section to help consumers choose the right car for their needs and provides tips on how to get discounts on cars.

In 1978, the magazine held its first Car of the Year Awards, giving advice on the best models to buy, and this has since been an annual – and eagerly awaited – feature. In 1996, the website www.whatcar.com was launched. More recently, What Car? launched another print edition in 2006, published in India every two months, which subsequently became a monthly publication.

What Car? was featured in the 2018 movie Early Man, though under the name What Chariot?.
