Karen is a suburb of Nairobi in Kenya, lying south-west of Nairobi's central business district. The suburb of Karen borders the Ngong Forest and is home to the Ngong Racecourse. Karen and Langata previously formed a somewhat isolated area of mid to high-income residents, but the two suburbs have become increasingly interconnected and linked to the rest of Nairobi through the expansion of the eponymous Langata Road and Ngong Road, the latter project completed in 2021.
