Lindsay Carole Ellis is an American film critic, YouTuber, cinematographer, and author. From 2008 to 2014, Ellis was part of the Channel Awesome production company under the web name "The Nostalgia Chick," a counterpart to the Nostalgia Critic. In 2014, she ended her affiliation with Channel Awesome to focus more on long-form video essays.

Ellis grew up in Johnson City, Tennessee, and received her BA in Film Studies from New York University in 2007 and MFA from USC School of Cinematic Arts in 2011. Along with her friends Elisa Hansen and Antonella "Nella" Inserra, she wrote Awoken, a paranormal romance parody of Twilight featuring a woman falling in love with Cthulhu, under the alias Serra Elinsen. In 2010, she wrote and directed the documentary short film "The A-Word" about women's experience with abortion. While studying for her MFA, Ellis was selected to host The Nostalgia Chick, a web series based on the Nostalgia Critic; she went on to create over 100 videos as part of the series before leaving in 2014.

On her YouTube channel, Ellis frequently makes videos about Walt Disney Pictures films. Other works include "The Whole Plate," a long-running series examining the Transformers film series and the work of Michael Bay which has received more than 4 million views, and a three-part series about the production of The Hobbit trilogy and its effect on the New Zealand film industry. Her Loose Canon series explores derivations of literary and film characters over time. Since 2017, her focus on her channel has been on video essays about films. Ellis says she most enjoys thinking about "things that are deeply flawed but have this really interesting potential." Her videos are created alongside a small team of part-time staff.

In addition to covering film topics, she has also created videos on being a YouTube content creator. Ellis also hosts the It's Lit! web series for PBS Digital Studios, which explores trends in American literature as a companion piece to The Great American Read on PBS itself.

The three-part documentary The Hobbit Duology (2018), which Ellis wrote and edited with Angelina Meehan, received a nomination for the 2019 Hugo Awards in the Best Related Work category.

Throughout her career online, Ellis has been subject to multiple campaigns of harassment.

In 2019, Ellis announced her debut novel, titled Axiom's End, to be released in July 2020.

Ellis is bisexual. She lives in Los Angeles.
