Three Cheers for the Irish is a 1940 comedy film directed by Lloyd Bacon, written by Richard Macaulay and Jerry Wald, and starring Priscilla Lane, Thomas Mitchell and Dennis Morgan.

The supporting cast features Virginia Grey, Alan Hale, Sr. and William Lundigan.

The plot involves a veteran police officer (Mitchell) forced into retirement only to learn that his replacement (Morgan), whom he detests, is romancing his daughter (Lane).

Maureen meets and falls in love with a Scottish policeman Angus Ferguson, Pat dates Ed Mckean, a wreaking supervisor who bores Peter and is a cheapskate, and Heloise who keeps time with a noted gambler- Joe Niklas.

Angus chases Peter when as a good Catholic and Irishman runs looking for a priest to make the wedding official.
