Our Only May Amelia is a 1999 American historical youth novel by Jennifer L. Holm.

Set in 1899 near Astoria, Oregon, it follows a young girl's coming of age amongst the region's Finnish community, and her life as the youngest of seven children—and the only girl—of Finnish immigrant parents.

The novel is based on diaries written by Holm's aunt.
