Marcella Almeida is a Brazilian voice actor known for her work in anime dubbing, having begun her professional career in 2020. Her path to voice acting was shaped by a long-standing passion for the art form, sparked in 2011 by the music from the Disney film Tangled. This interest led her to take her first dubbing course in 2014, followed by theater training starting in 2015, and ultimately a professional dubbing course in 2018 before landing her first role.

Almeida has quickly become a prominent voice in the Brazilian dubbing industry, voicing a wide array of leading and supporting characters in popular anime series. She is widely recognized for her portrayal of the titular character Kaguya Shinomiya in the romantic comedy Kaguya-sama: Love is War, a role she describes as her first protagonist and a significant personal favorite. Her other notable anime roles include Isuzu Soma in Fruits Basket, Nagato in Azur Lane, Aoi Sangu in Seraph of the End, and Fine Tybur in Attack on Titan. Her repertoire also encompasses characters such as Miorine Rembran in Mobile Suit Gundam: The Witch from Mercury, and she has voiced roles in series like Dr. Stone and Laid-Back Camp.

Almeida's work is often conducted at studios like Atma Entretenimento, where she was directed by Lucas Almeida in the dubbing of Mobile Suit Gundam: The Witch from Mercury. She has spoken about the challenges and range required in her craft, citing roles that demanded a more masculine vocal register and energy for characters in Laid-Back Camp and Masamune-kun's Revenge, as well as a very deep voice for an unnamed project. Among her achievements, she considers voicing Kaguya Shinomiya a pivotal learning experience, praising the role for its emotional breadth from comedic outbursts to dramatic moments. Beyond anime, she has also voiced the character Elize in the series Warrior, a role she found personally fulfilling as it allowed her to work in a period piece.
