Mistress Pat (1935) is a novel written by Canadian author L. M. Montgomery, noted for her Anne of Green Gables series.

Mistress Pat is the sequel to Pat of Silver Bush, and describes Patricia Gardiner's life in her twenties and early thirties, during which she remains unmarried and takes care of her beloved home, Silver Bush, on Prince Edward Island.

Pat's older brother, Sid, suddenly marries the loud and opinionated May Binnie after he is jilted by another woman.

Sid and May's marriage is an extremely unhappy one, May making enemies of all her in-laws, alternately screaming, sulking, and throwing things.

Pat's younger sister Rachel, aka Cuddles, demands that everyone call her Rae from now on, and leaves for college.

After finally deciding to visit her late friend Bets Wilcox's former home, Pat stumbles across new neighbors David and Suzanne Kirk, brother and sister.

When he finally finds the chance to propose she accepts, contented with the thought of always watching over Silver Bush.

Years pass, and Pat becomes comfortable with the idea of marrying David, until Hilary returns for a brief visit to Silver Bush.

He plays the fiddle and tells outrageous stories, much to the consternation of Judy Plum, though she holds him in enough affection to make him his favourite treats.

Hilary "Jingle" Gordon: Pat's childhood friend, who for the majority of the novel is studying architecture at college and overseas.
