Tiffany Hsieh is a name used as a pseudonym in the English-language dubbing industry for anime and other media. While not a separate professional identity, the credit Tiffany Hsieh is recognized as an alternate stage name for the established American voice actress, ADR director, and producer Stephanie Sheh, who has also worked under the names Jennifer Sekiguchi and Lulu Chiang.

Primary voice roles were performed under the name Tiffany Hsieh in the mid-2000s for several anime series produced in Los Angeles. One of the most notable roles is Aya Natsume in the series Tenjho Tenge, a character known for her energetic and determined personality within the martial arts-focused story. Another key role credited to Tiffany Hsieh is Nanoka Kohinata in the series Koi Kaze, a dramatic and complex narrative that explores the relationship between two siblings.

The use of the name Tiffany Hsieh appeared during a specific period of the voice actor's career, likely for credit flexibility or to comply with union regulations, a common practice in the voice-over industry at the time. In addition to the roles in Tenjho Tenge and Koi Kaze, the credit appears in other productions from this era. For instance, the voice actor used the Tiffany Hsieh name for the role of Osaka in the popular comedy series Azumanga Daioh. These performances as Tiffany Hsieh are part of a broader career that includes hundreds of other credits, such as the iconic roles of Hinata Hyuga in Naruto and Orihime Inoue in Bleach, though those are not associated with this particular alias. The body of work under the name Tiffany Hsieh represents a subset of early English dub performances from the 2000s.
