Rubina Kuraoka, later known professionally as Rubina Nath, is a German voice actor of Japanese descent who has built a prolific career spanning animation, anime, and live-action dubbing. She was born on October 17, 1987, in Berlin, Germany. Her entry into the field was facilitated by her mother, who worked as a recording director at Bikini Studios, also known as Kuraoka Entertainment.

Kuraoka became a prominent voice for numerous anime series, particularly during the 2000s. She provided the German voice for a wide range of characters, including the exceptionally bright and young Chiyo Mihama in Azumanga Daioh. She also voiced the titular young boy wizard Negi Springfield in the Negima!? series and its OVAs. Another notable role was the small, rabbit-like creature Mokona in both Tsubasa Chronicle and ×××HOLiC. Her versatility extended to voicing the enigmatic and often unsettling Incubator Kyubey in Puella Magi Madoka Magica, as well as roles in other major titles such as Nana in Elfen Lied, Kaho Fujitani in The Girl Who Leapt Through Time, Koyomi Yoimachi in Zombie-Loan, Yuzuriha Nekoi in X, Yukino Miyazawa in Kare Kano, Téa Gardner in Yu-Gi-Oh!, and Rima Tōya in Vampire Knight.

Beyond anime, her voice became widely recognized in other areas of animation. She took over as the voice of Littlefoot in the German versions of the In einem Land vor unserer Zeit (The Land Before Time) film series and voiced Daphne Blake in various Scooby-Doo productions. She also became known to a younger generation as the voice of Rarity in the popular series My Little Pony: Freundschaft ist Magie (My Little Pony: Friendship is Magic) and its subsequent films.

Kuraoka's career eventually expanded to become one of the most in-demand German voices for international live-action film and television. She is the standard German voice for actresses such as Dakota Johnson, Karen Gillan, and Lupita Nyong'o. This work includes voicing Carly Shay in the live-action series iCarly for Miranda Cosgrove, Bailey Pickett in Zack & Cody an Bord for Debby Ryan, and Sybil Crawley in Downton Abbey for Jessica Brown Findlay. Under her married name, Rubina Nath, she has also narrated audiobooks and continues to work extensively in dubbing for major Hollywood and international productions.
