The reunion will include stars such as Matthew Morrison, who played teacher Will Schuester;Jane Lynch, who played cheerleading coach Sue Sylvester, and Heather Morris, who played Rivera's brief on-screen partner, Brittany.
The tribute will mark the 10-year anniversary of Rivera's character coming out as gay on the show, as well as shine a spotlight on her impact on LGBTQ+ teenagers and the Latinx community.
Singer Demi Lovato, who played Rivera's girlfriend later on the show, will introduce the special tribute at the awards show on 8 April.
Amber Riley, who played Mercedes; Chris Colfer, who played Kurt and Darren Criss, who played Blaine, will also appear in Rivera's tribute.
Rivera was found dead in Lake Piru, northwest of Los Angeles, after being reported missing on 8 July.
A report into her death said that she had helped her then-four-year-old son, Josey, back on the boat she had rented, before she "disappeared in to the water".
The boy was found sleeping on the boat later that afternoon and Rivera's body was found floating in the lake five days later.
