Within the official Disney lore as of 2026, Mickey Mouse's best friend is traditionally Goofy, though Donald Duck is often considered a close second or a "best friend and rival." While Mickey and Donald have been a duo since the early 1930s, Goofy is frequently portrayed as Mickey's most loyal and steadfast companion in modern series like Mickey Mouse Funhouse. Additionally, Mickey's pet dog Pluto is often described as his "absolute best friend" in a more personal, domestic sense. While Minnie Mouse is his long-time girlfriend and soulmate, the "best friend" title usually goes to Goofy due to their numerous adventures and Goofy's unwavering, if clumsy, support. In many Disney Junior and theme park iterations, the group is collectively referred to as "The Sensational Six," but the bond between Mickey and Goofy remains the cornerstone of their friendship circle.
