Adaline Weston Couzins (August 12, 1815 – May 9, 1892) was a British-born American civil servant, a suffragist, and a Civil War nurse who worked for the Ladies' Union Aid Society of St. Louis. She spent most of her career as a nurse during the Civil War on hospital ships that tended to Union and Confederate soldiers all along the Mississippi River. Adaline moved to St. Louis, Missouri around 1823 from England and eventually married John Edward Decker Couzins in 1834. Adaline and John had four children. Their daughter, Phoebe Couzins, was one of the first female lawyers in the United States.
