I Can't Understand What My Husband Is Saying (旦那が何を言っているかわからない件, Danna ga Nani o Itteiru ka Wakaranai Ken) is a Japanese 4-panel manga series by Coolkyousinnjya.

The series centers around the daily lives of Kaoru, a hard working office lady, and her husband Hajime, who is an otaku, an obsessed fan of anime and manga culture, and who works as a blogger.

The witty dialogue accentuates the animation and sometimes slips into manzai-style[jargon] humor.

An anime television series adaptation began airing in October 2014.

The thirteenth episode announced that the series had been green-lit for a second season, which premiered in April 2015.
