The Lexus ES series is a mid-size luxury sedan sold by Lexus since 1989. Six generations of the sedan have been introduced to date, each featuring V6 engines, automatic transmissions, and front-wheel drive. The first five generations of the ES were built on the Toyota Camry platform. Manual transmissions were offered until 1993, a lower-displacement inline-four engine became an option in Asian markets in 2010, and a gasoline-electric hybrid version was introduced in 2012. The ES was Lexus' only front-wheel drive vehicle until 1999, when the related Lexus RX 300 arrived, and the sedan occupied the entry-level luxury car segment of the Lexus lineup in North America and other regions until the debut of the Lexus IS in 1999.

Introduced in 1989, the first generation ES 250 was one of two vehicles in Lexus' debut lineup, the other being the flagship LS 400. The second generation ES 300 debuted in 1991, followed by the third generation ES 300 in 1996, and the fourth generation ES 300/330 in 2001. The first through fourth generation sedans shared body styling elements with Japan-market Toyota sedans, and a domestic market equivalent, the Toyota Windom (トヨタ・ウィンダム), was sold until the launch of the fifth generation ES in 2006. The fifth generation ES, featuring Lexus' own L-finesse body styling, debuted in early 2006 as a 2007 model. The sixth generation ES debuted in the first half of 2012 as a 2013 model.
