Michaela Jill Murphy is an American voice actress. She is best known for voicing Toph Beifong in Avatar: The Last Airbender and Chaca in Kronk's New Groove and The Emperor's New School.

​

In 2005, Murphy voiced Meng in an episode of the Nickelodeon animated series Avatar: The Last Airbender. Her performance convinced creators Bryan Konietzko and Michael Dante DiMartino to cast her as main cast member Toph Beifong because of the "energy" she brought to the role. Murphy later told The Tab that she continued voicing Toph until her first year in high school and called the role her favorite voice acting experience and said she felt "pretty connected" to Toph's character, although she was only eleven years old when she was cast. She would also describe the second-season episode "The Library" as one of her favorite episodes in the series.

In 2014, Murphy guest-starred in The Legend of Korra as Toph's daughter Suyin Beifong. It was later described as helping lay the groundwork of Suyin's "personality while also paying tribute to her original role."
