Lexus is the luxury vehicle division of Japanese automaker Toyota Motor Corporation. Lexus brand name vehicles are sold in North America, Europe, Asia, the Middle East, Oceania, Africa, and Latin America; in the United States, Lexus is the highest-selling make of luxury cars. In 2005, the Lexus marque launched in Japan, marking the continued global expansion of the luxury division.

Since its debut in 1989, Lexus has developed a reputation for the luxury and reliability of its vehicles, along with the quality of its customer service. In 2007, consumer ratings firm J.D. Power and Associates named Lexus the most reliable brand in the U.S. based on its Vehicle Dependability Survey, a measure of over 53,000 vehicle owners and the problems they experienced in the first three years of vehicle ownership. It was the thirteenth consecutive year that Lexus achieved this top rating. In recent years, Consumer Reports has also named Lexus among the top five most reliable brands in its Annual Car Reliability Surveys of over one million vehicles nationwide. Additionally, Lexus ranks highly on surveys of dealership service experience. The British Top Gear and Auto Express satisfaction surveys have had Lexus at the top of their ratings since the entry of the luxury division, with reliability and quality among the main selling points of Lexus around the world.

Lexus' slogan is The Passionate Pursuit of Perfection.
