(Note: If you are looking for information regarding the voice actors behind the beloved character Uncle Iroh from Avatar: The Last Airbender, this guide covers both the original animated series, spin-off media, and the 2026 live-action landscape.)
The character of Uncle Iroh in Avatar: The Last Airbender remains one of the most beloved, complex, and philosophically profound figures in modern television history. Central to his enduring legacy is the brilliant voice acting that brought his warmth, wisdom, and sorrow to life. Understanding who voiced Uncle Iroh requires looking at the remarkable talents who shaped the character across different mediums, most notably Mako Iwamatsu and Greg Baldwin. As we navigate the entertainment landscape in 2026, exploring the history, impact, and technical artistry of these performances offers vital insight into animation history.
The Legendary Original Voice: Mako Iwamatsu in Seasons 1 and 2
The foundation of Uncle Iroh's voice and soul was established by the legendary actor Mako Iwamatsu, professionally known simply as Mako. Born in Kobe, Japan, before becoming a titan of American stage, film, and television, Mako brought an authentic cultural depth and a lived-in gravitas to the role of the retired Fire Nation general.
Mako voiced Uncle Iroh throughout Season 1 and the majority of Season 2 of the original Nickelodeon animated series. His vocal performance was characterized by a rich, gravelly resonance that effortlessly shifted from stern discipline to paternal tenderness. Furthermore, Mako imbued Iroh with a distinct gentle humor, whether the character was enthusiastically enjoying a cup of jasmine tea or lazily napping in the sun.
Key attributes of Mako's historic portrayal include:
- Cultural Authenticity: Mako infused Iroh's pronunciation of Eastern concepts, names, and tea varieties with genuine linguistic familiarity.
- Emotional Range: He balanced the heavy dramatic weight of Iroh's tragic past with lighthearted, whimsical eccentricities.
- Musicality: Mako delivered iconic musical moments, most notably the deeply moving song "Leaves from the Vine" featured in the "Tales of Ba Sing Se" episode.
Tragically, Mako passed away from esophageal cancer in July 2006 during the production of Season 2. His death marked a profound loss for the entertainment industry and the production team behind Avatar: The Last Airbender, leading to a dedicated tribute episode in Season 3 titled "The Tales of Ba Sing Se," which concluded with the heartbreaking dedication, "In Honor of Mako."
The Seamless Transition: Greg Baldwin in Season 3 and Beyond
Following the passing of Mako, the production team faced the monumental task of finding a successor who could honor Mako's legacy without disrupting the audience's emotional connection to Uncle Iroh. Enter Greg Baldwin, who had previously served as Mako's understudy and voice double on other projects.
Greg Baldwin stepped in to complete Iroh's lines in Season 2 and took over the role entirely for Season 3, including the epic climax of the series. Baldwin's audition and subsequent performance stunned both the crew and the fans due to his uncanny ability to replicate Mako's vocal cadence, pitch, and emotional warmth.
Voice Actor Continuity Note: Greg Baldwin did not merely imitate Mako; he studied Mako's vocal patterns meticulously to ensure that viewers experienced zero jarring transitions when hearing Uncle Iroh speak during the pivotal final arcs of the animated series. This seamless continuation set a high standard for vocal replacement in the animation industry.
In the years following the original series, including video game adaptations and subsequent franchise expansions, Greg Baldwin became the definitive ongoing voice of Uncle Iroh, cementing his own vital place in the franchise's history.

Expanding the Legacy: Voice Casting Across Spinoffs and Media
The influence of Uncle Iroh extends far beyond the original 61 episodes of the 2005 animated series. As the franchise expanded into multi-platform media, the voice of Uncle Iroh required careful stewardship.
When the sequel series The Legend of Korra aired, the character of Uncle Iroh reappeared in older iterations within the Spirit World. Greg Baldwin reprised his role, portraying a peaceful, enlightened spirit who assists Avatar Korra and her friends. Additionally, various video game adaptations, such as Avatar: The Last Airbender – Into the Inferno, relied on Baldwin to maintain consistency.
Live-action adaptations present a different approach to character portrayal. In the live-action television landscape, physical actors take on the visual role of Uncle Iroh, performing the dialogue natively rather than dubbing over animation. However, the vocal cadences established by Mako and carried by Baldwin continue to serve as the definitive blueprint for how Iroh is interpreted by modern actors and directors alike.
