Gardein (a portmanteau of garden and protein) is a line of meat-free foods produced by Conagra Brands. In 2003, the company was founded by Yves Potvin, who remained as the CEO of Gardein until 2016. In November 2014, Pinnacle Foods purchased Gardein for $154 million. Pinnacle was acquired by Conagra in 2018.

The company has production facilities in Richmond, British Columbia and Hagerstown, Maryland. All of Gardein's products are vegan. The company uses a proprietary process to make its meatless products. In 2014, the company began producing gluten free meatless products.

Garden Protein International was founded by former chef Yves Potvin in 2003. In 2009, the company began selling its frozen products.

In 2007, Garden Protein had 85 employees and $50 million in annual sales. In 2014, it had nearly $100 million in sales at the retail level. By 2015, it had over 250 employees with distribution to more than 22,000 stores in North America.

Gardein was first used in the United Kingdom in 2008, as an ingredient in Grassington's frozen meals.

Gardein products have been featured on The Oprah Winfrey Show multiple times by chef and Gardein consultant Tal Ronnen.

In 2013, Gardein partnered with the Los Angeles City Council to celebrate Meatless Monday.

In 2007, Gardein received PETA's Company of the Year Award for their meat substitute products.
