The Koenigsegg Regera is a limited production, plug-in hybrid grand touring sports car manufactured by Swedish automotive manufacturer Koenigsegg. It was unveiled at the March 2015 Geneva Motor Show. The name Regera is a Swedish verb, meaning "to reign" or "to rule." Koenigsegg planned to produce only 80 units of the car, many of which were sold upon unveiling, though 84 Regera chassis were constructed.

The Regera was developed and designed to be a more practical, luxurious, grand touring alternative to the rest of Koenigsegg's lightweight sports car lineup; initially the Agera and currently the Jesko. As a result, it is less focused on-track performance and spartan weight reduction and more focused on the smooth and instant delivery of power provided by its overhauled powertrain. Koenigsegg states that the Regera will be one of the most powerful and fastest-accelerating hybrid production cars produced.

The introduction of the Regera alongside the Agera RS in 2015 resulted in Koenigsegg, for the first time ever, simultaneously having two models in production.[10] This role was passed from the Agera to the Jesko in 2019, which briefly shared the production line with the Regera when Jesko production began in late 2021.
