Strictly Modern is a 1930 American pre-Code comedy film directed by William A. Seiter and starring Dorothy Mackaill and Sidney Blackmer.

It was produced and released by First National Pictures and was based on the play, entitled Cousin Kate, written by Hubert Henry Davies.

When she falls in love, she plans to act exactly like the heroines in her novels and expects her future boyfriend to do likewise.

As the film begins, we find out that Mackaill's cousin, Aimee (Johnston) is about to be married to Heath Desmond (Blackmer).

When Kate learns that Heath is her cousin's fiancé, she pretends that she had only been flirting because she thinks that falling in love with a man who is about to marry someone else is not appropriate.
