Old Lady 31 is a 1920 American silent comedy-drama film produced and distributed by Metro Pictures and directed by John Ince.

It is based on a novel by Louise Forsslund that was turned into a play by Rachel Crothers.

The film starred actress Emma Dunn reprising her 1916 stage success for the screen.

Based upon a summary of the plot in a review in a film publication,[3] Angie (Dunn) and Abe (Harmon) have been married for many years when bad investments force them to sell their homestead.

When some apparently worthless mining stock is found to have some value, the couple are able to return to their home.
