The Lexus ES series is a family of mid-size luxury sedans produced by the Lexus division of Toyota since 1989. Now in its fifth generation, the series has been consistently built on the Toyota Camry platform with a V6 engine, automatic transmission, and front-wheel drive. The first generation ES 250, built from 1989 to 1991, shared the body style of the contemporary Camry, while the Toyota Windom, a Japan-only model, shared the ES' body style from the 1992 second generation until 2006. The current fifth generation ES 350, featuring Lexus' own L-finesse body styling, was unveiled in the spring of 2006 as a 2007 model.

For much of its existence, the Lexus ES has anchored the entry-level luxury car segment of the Lexus lineup in North America, a position it maintained until the introduction of the Lexus IS sport luxury sedans in 2001. Like the previous generation ES 330 model, the current fifth generation ES 350 is geared towards the comfort luxury segment, with an emphasis on interior amenities, quietness, and a smooth ride. For the past fifteen years, the Lexus ES has been the best-selling Lexus sedan in the United States. Dawson, Chester. Lexus: The Relentless Pursuit. 2004: Jon Wiley & Sons, NJ.
