Tasti D-Lite is a New York-based company best known for its signature product, a frozen dessert comparable to, but marketed as a healthier alternative to soft serve ice cream. The company operates a system of franchise chain stores from which its products are sold in trademark blue paper cups. The stores are predominantly located in New York state, although the company's corporate headquarters are now in Tennessee.

The treat has attained widespread popularity since its 1987 creation, at least partly due to aggressive advertising claiming extremely low calorie and fat content. In 2002, published studies  found that the company may have greatly exaggerated claims of its product's healthfulness. Tasti D-Lite subsequently implemented an overrun compliance program and settled the nutritional claims matter with the NYC Department of Consumer Affairs.

In 2004, the popularity of Tasti D-Lite was bolstered as a result of appearances in episodes of HBO’s Sex and the City season 6 episode 88  and The Apprentice season 2 episode 18.

Tasti D-Lite was acquired in 2007 by NY-based private equity group SPG Partners LLC and announced that James H. Amos, one of the firm's operating partners, will serve as Chief Executive Officer of Tasti D-Lite. The new company would be headquartered in Franklin, Tennessee.

A redesigned website was launched in 2007 listing nutritional information for over 100 flavors. Tasti D-Lite announced in 2008 that it will begin a franchise offering to facilitate the growth of the brand to markets both domestic and international. Subsequently, a majority of the original licensed stores signed agreements to convert to the franchise model. Also in 2008, the first international development agreement was signed for South Korea.
