The Honda Ascot was a intermediate saloon car (mid-size sedan) manufactured by Honda and marketed in Japan only from 1989 to 1997. There were two generations of the car, based on the contemporary Honda Accord and Honda Inspire, respectively. Additionally, from 1993 to 1996 a "pillared hardtop" model based on the Accord was marketed in Japan as Honda Ascot Innova, being equivalent to the Swindon-made European-market Accord at that time.

The "Ascot" name was chosen with reference to the Ascot Racecourse and Ascot tie, in order to add the model an alleged air of class and elegance.

The first Honda Ascot was borne out Honda's strategy to diversify its sales channels in Japan. In 1985, two separate dealer networks were established, under the names of "Honda Clio" and "Honda Primo", in addition to the already existing "Honda Verno" network. While the Primo stores handled kei cars, as well as base Honda Civics, the Clio stores focused on larger models, including the top-of-the-line Honda Legend. With the arrival of the fourth-generation Honda Accord (CB), its sales were assigned solely to Honda Clio.

That meant, however, that the Honda Primo network needed a new intermediate-size car. Honda adopted a rather simple solution (quite common in such cases in the JDM market) of creating a "sister car" to Accord, the Honda Ascot. Technically, the Ascot was identical to the Accord saloon, and so was most of the body, but some cosmetic differences provided for a different look, befitting the Ascot's upmarket role as the top-of-the-line model of Honda Primo. The Ascot had a six-light greenhouse compared to the regular Accord's four-light layout, and featured a different front end with a more formal grille, as well as a revised rear end with a unified light belt.
