Megan Stalter (born September 15, 1990) is an American comedian and actress.

She is most famous for playing Kayla Schaeffer in the HBO comedy series Hacks (2021-2026) and Jessica Salmon in Lena Dunham's Netflix series Too Much (2025).

In her viral online videos, Stalter specializes in desperate, deluded characters who are prone to theatricality, frequent mispronunciations, and botched suicide attempts. "I feel like all my characters are people whose lives didn't turn out a certain way, but they're still trying to pretend like it did," Stalter has said. In 2019, she joined the cast and writing staff of the reboot of The National Lampoon Radio Hour. She is also the host of the webseries The Megan Stalter Show and the Forever Dog podcast Confronting Demons with Megan Stalter.
