’It’s Always Sunny in Philadelphia’ Star Changing His Name?

In a move that blends personal branding with practical necessity, It’s Always Sunny in Philadelphia star and co-creator Rob McElhenney has officially filed to change his name to Rob Mac.

The decision, confirmed by McElhenney himself, marks a significant shift for the actor, writer, and entrepreneur whose surname has long been a source of confusion—and comedy. McElhenney, whose last name has famously stumped fans and media alike (despite Ryan Reynolds’ musical pronunciation tutorial), cited global business expansion as the primary reason. As his company, More Better Industries, continues to invest internationally—including ventures in Colombia and Mexico—he found that “McElhenney” was often mispronounced or misunderstood. “As our business and our storytelling is expanding into other regions of the world and other languages in which my name is even harder to pronounce, I’m just going by Rob Mac,” he told Variety.

Interestingly, the name “Mac” isn’t just a simplification—it’s also a nod to his iconic Always Sunny character, known simply as Mac. It’s a full-circle moment that blends his personal identity with his pop culture persona. The name change is already being reflected in FX press materials for both It’s Always Sunny and Welcome to Wrexham, the Emmy-winning docuseries chronicling McElhenney and Reynolds’ ownership of Wrexham AFC.
