Who portrays Roger Sterling on Mad Men?

John Slattery portrays Roger Sterling on Mad Men. Roger is a managing partner of Sterling Cooper and the son of the agency’s late co-founder, Roger Sterling Sr.

Roger’s position gives him authority, wealth, and access to influential clients, but his personal life is often unstable. He is charming, witty, and socially connected, yet prone to infidelity, excess, and emotional avoidance. His relationship with Lucky Strike, one of Sterling Cooper’s most important accounts, is central to the agency’s early success.

Slattery’s performance balances Roger’s comic confidence with the character’s vulnerability. Roger is not the agency’s creative leader—that role belongs primarily to Don Draper—but he is an important business and political force within the firm. After Sterling Cooper changes ownership, he becomes a founding partner of Sterling Cooper Draper Pryce.

A frequent mix-up involves Jared Harris, who plays British financial executive Lane Pryce, or Robert Morse, who plays senior partner Bert Cooper. Harry Hamlin appears as advertising executive Jim Cutler, not Roger Sterling.
