GMA3: What You Need to Know is a daytime news program that airs on ABC in the United States. In March 2020, due to the COVID-19 pandemic, the show suspended its in-studio audiences. Later, ABC replaced Strahan, Sara & Keke with Pandemic: What You Need to Know, a daytime newscast produced by ABC News' streaming channel ABC News Live. The temporary replacement was anchored by Amy Robach and featured contributions from ABC News' chief medical correspondent, Jennifer Ashton.

The program evolved into a general daytime newscast in the months that followed and was eventually renamed GMA3: What You Need to Know. The show increased its coverage of stories unrelated to COVID-19 and made the What You Need to Know format permanent. T.J. Holmes was announced as a new co-anchor in September 2020, and the program received a new logo and graphics package based upon Good Morning America.

In December 2022, co-anchors T.J. Holmes and Amy Robach were temporarily placed on leave after it was reported that they were in a romantic relationship. Rhiannon Ally and DeMarco Morgan began to serve as fill-ins at this time. In January 2023, it was announced that Robach and Holmes would depart the program after an investigation into their alleged affair, and no official replacements have been named for the two.
