Rebecca Wang is a trilingual Asian-American voice actor based in Los Angeles, California. Her career in voice-over began in animation, where she was initially responsible for running scratch sessions, a process where temporary voices are recorded to guide animators. This experience led her to begin performing voices herself, providing scratch tracks for lead animated characters in series such as Dreamworks Animation's Jurassic World Camp Cretaceous, Guillermo del Toro's Tales of Arcadia Trilogy, and the Netflix series Blue Eye Samurai.

Wang is known for her work in English dubs of anime and video games. She voices the character Sung Jinah, the younger sister of the protagonist, in the English adaptation of the popular anime series Solo Leveling. She reprised this role for the 2024 compilation film Solo Leveling -ReAwakening-, which also previewed the first episodes of the series' second season. In 2025, she joined the English dub cast of the highly anticipated anime film Demon Slayer: Kimetsu no Yaiba Infinity Castle, providing the voice for the character Koyuki.

Beyond these major anime titles, Wang has lent her voice to several video games. Her notable roles in the gaming industry include characters in Fire Emblem Shadows, Pokemon Masters, Nikke: Goddess of Victory, and Cookie Run Kingdom.
