Adaś Miauczyński is a fictional character created by Marek Koterski.^[1] He has featured in a series of films and stage works as well as a musical. Adaś (in two films, he is presented as Michał Miauczyński) is a Polish man whose first name, Adaś, is a diminutive form of Adam, while Miauczyński is a wordplay derived from "meow", a sound produced by cats. He is a vulgar, neurotic, and frustrated intellectual who either lives alone or with his ex-wife, and sometimes with his children.

The character has appeared in nine feature films: Dom wariatów (1984), Życie wewnętrzne (1987), Porno (1989), Nothing Funny (1995), Ajlawju (1999), Day of the Wacko (2002), We're All Christs (2006), Baby są jakieś inne (2011), and 7 uczuć (2018). Each story showcases a different aspect or era of his life, often with little continuity between them. He has been portrayed by different actors, both on stage and onscreen.

In 2017, a musical about Miauczyński, based on Day of the Wacko, was released.^[2]
