Carmilla is a Canadian single-frame web series co-created by Jordan Hall, Steph Ouaknine, and Jay Bennett. The series stars Elise Bauman and Natasha Negovanlis, and is loosely based on the novella of the same name by Sheridan Le Fanu. The series premiered on the Vervegirl (rebranded as KindaTV as of January 2016) YouTube channel on August 19, 2014. U by Kotex is the executive producer of the web series. The series takes place at the fictional Silas University in Styria, Austria, and is told through vlogs recorded by Laura, a first-year student. When Laura begins investigating the disappearance of her roommate, she is assigned a new roommate named Carmilla.

The first and second seasons each consist of 36 three to seven-minute episodes. A twelve-episode prequel mini-season, "season zero," was announced just after the release of the final episode of season 2. On February 13, 2016, it was announced that Carmilla would air its third and final season in the summer of 2016. The third season was eventually released in September and October 2016, in three acts. On October 6, 2016, it was announced that there would be a movie (not sponsored by U by Kotex) that would take place five years after the end of the third season. The film, called The Carmilla Movie, was released in 2017. At the Canadian Screen Awards in 2018, it was announced by Elise Bauman that an unnamed prime time series was in development.

In 2016, the series won a Canadian Screen Award and a Rockie Award for Branded Content at the Banff World Media Festival. As of August 2017, Carmilla had generated over 70 million views on YouTube.
