The Little Women Trilogy includes three novels about the four March sisters Meg, Jo, Beth and Amy.

Little Women is a novel by American author Louisa May Alcott, which was originally published in two volumes in 1868 and 1869. Alcott wrote the books over several months at the request of her publisher. Following the lives of the four March sisters - Meg, Jo, Beth and Amy - the novel details their passage from childhood to womanhood and is loosely based on the author and her three sisters. Scholars classify Little Women as an autobiographical or semi-autobiographical novel. Little Women was an immediate commercial and critical success, with readers demanding to know more about the characters. Alcott quickly completed a second volume (entitled Good Wives in the United Kingdom, although this name originated from the publisher and not from Alcott). It was also successful. The two volumes were issued in 1880 as a single novel entitled Little Women.

Little Men, or Life at Plumfield with Jo's Boys, is a novel by American author Louisa May Alcott, first published in 1871. The novel reprises characters from Little Women and is considered by some the second book in an unofficial Little Women trilogy, which is completed with Alcott's 1886 novel Jo's Boys, and How They Turned Out: A Sequel to "Little Men". It tells the story of Jo Bhaer and the children at Plumfield Estate School. It was inspired by the death of Alcott's brother-in-law, which reveals itself in one of the last chapters, when a beloved character from Little Women passes away.

Jo's Boys, and How They Turned Out: A Sequel to "Little Men" is a novel by American author Louisa May Alcott, first published in 1886. The novel is the final book in the unofficial Little Women series. In it, Jo's children, now grown, are caught up in real world troubles.
