Ariel is a 1988 Finnish drama film directed and written by Aki Kaurismäki. The film tells the story of Taisto Kasurinen (Turo Pajala), a Finnish miner who must find a way to live in the big city after the mine closes.

Taisto's friend is played by Matti Pellonpää, an actor who appeared in many of Kaurismäki's early films, before his death in 1995.

This is the second film in Kaurismäki's Proletariat Trilogy (Shadows in Paradise, Ariel, and The Match Factory Girl). The trilogy has been released on Region One DVD by Criterion in its Eclipse box-sets. The film is included in the 1001 Movies You Must See Before You Die list. The film was entered into the 16th Moscow International Film Festival, where Turo Pajala won the Bronze St. George for Best Actor.

Kaurismäki has called Ariel his best film in his career.
