The Lexus ES series is a family of midize sedans produced by the Lexus division of Toyota from 1989 to the present. The Lexus ES was built in Tsutsumi, Japan. The first ES250 was built on August 30, 1989. The last ES250 was built on July 5, 1991. The first ES300 was built on September 9, 1991 as a 1992 model. The ES series has always been built off of the Toyota Camry platform and features a V6 engine and automatic transmission. The Camry and ES do generally not directly compete, as the ES offers a more upscale ride, more elegant styling, and more luxury features. From the second generation onwards, the ES is sold in Japan as the Toyota Windom.

The fifth-generation ES debuted at the Chicago Auto Show in February of 2006. It is based on the Toyota Avalon and will arrive at dealerships in the spring as a 2007 model.
