Overthinking with Kat & June is an American comedy series, created by Mackenzie Yeager, that premiered on December 19, 2018, on YouTube Premium.

The series stars an ensemble cast featuring Alexia Dox, Tenea Intriago, Sasheer Zamata, Blake Lee, Elizabeth Hinkler, Emily Hinkler, Burl Moseley, Madeleine Byrne, Montana Roesch, Justin Kirk, Kelli Goss, Jessika Van, Aaron Takahashi, Kevin Bigley, Nick Fink, Stephen Ellis, Constance Marie, David L. King, and Amanda Foreman.

Executive producers for the series are set to include Shelley Zimmerman, Shauna Phelan, Yeager, and Braeden.

"[5] In another favorable critique, Metro US' Andrew Husband described the series as "an occasionally surreal blend of laugh-out-loud comedy and absolute cringe.

From Kat and June's frequent fantasizing about their older landlord David to the former’s attempts to prepare the latter for a first date with the help of the twins Tessa and Molly, Overthinking can sometimes emphasize the "over" in its title.
