SD Entertainment, Inc. (more commonly known as Sabella-Dern Entertainment) is a dormant American animation studio specializing in entertainment for children. The "SD" in the initials of the company name stand for Sabella Dern, the respective last names of its founders: former MGM Animation employees Paul Sabella and Jonathan Dern and was founded in 1999.

The company is based in Woodland Hills, California. It owned two subsidiaries, Kidtoon Films and The Bigger Picture, that both also founded by Jonathan Dern, deal with the distribution of SD's productions in digital venues across the United States. They were eventually acquired by Cinedigm (now Cineverse) in 2007.

As of 2026, the company, despite still existing, has been dormant since 2011.
