Zero-G, Inc. (Japanese: 株式会社ゼロジー, Hepburn: Kabushiki-gaisha Zerojī) is a Japanese animation studio founded in June 2011 by veteran anime director Hiroshi Negishi.

The studio is located in Suginami, Tokyo.

In June 2015, Sakikawa Yukiya, a former animation producer at AIC PLUS+, was appointed CEO of Zero-G.[3] The studio is separate from Negishi's prior studio Zero-G Room, which was established in 1991 and was later shut down in 2001 when it merged with Radix to become Radix Ace Entertainment.

As of April 2023, Zero-G operates as a subsidiary of NOIX and is a group company of Saber Project, an entertainment company founded by Negishi in 2014.
