Side Streets, also known in the UK as A Woman in Her Thirties, is a 1934 American romantic melodrama directed by Alfred E. Green.

The film stars Aline MacMahon, Paul Kelly, Ann Dvorak and Dorothy Tree.

Middle-aged spinster Madame Valerie (real name is Bertha) (MacMahon) hires derelict sailor Tim O'Hara (Kelly) to work in her fur shop.

Bertha, being so kind hearted, went to the girlfriend and gave her "Tim's last weeks pay" and promises to help often financially.

The New York Times film critic Mordaunt Hall panned Side Streets, calling it "one of those wearying examples of writing down to what the studio believes to be the intelligence level of certain cinema audiences."
