Dior Homme is the menswear division of Christian Dior SA, the French clothing retailer. Dior Men has been under the creative direction of Kim Jones since spring/summer 2019. It had been directed by Hedi Slimane since the fall/winter 2001-02 season. Under Hedi Slimane's direction, Dior Men has introduced a characteristic slim silhouette which has since taken off within the fashion industry. The early collections delved into the exploration of the male sex. The look darkened during the Luster period which was inspired by the electroscene of Berlin. Since 2004 A/W, Dior Men has delved into exploring the different styles of Rock and Roll. The logo currently used by Dior Men is a bee, usually in the bottom right-hand side of knitwear and the top right side in polo shirts.

Since 2007 and the departure of Hedi Slimane, Kris Van Assche implements a more formal and minimal style. Over the seasons, he softens the black stiff silhouette which had become too cliché and opt for models who add an athletic look to the spindly Dior Men silhouette. This new look is characterized by attention to details and color palette of shades of black, gray, blue or brown.

During the 1980s and 1990s Dior's menswear line was called Dior Monsieur.

In late 2007 Dior Men began producing a six-piece men's skin care range, with Hedi Slimane designing the packaging. The skin care range is available for sale in France and department stores in many other countries.

Since March 2018, the Dior menswear line is called Dior Men instead of Dior Homme. The change was under the influence of creative director Kim Jones.
