Katalin Bánffy de Alsólindva (Hungarian pronunciation: [ˈkɒtɒlin ˈbaːnfi]) was a 16th-century Hungarian noblewoman, the wife of general and politician Ferenc Batthyány.
Her husband spent much of his time away from home at war, or in assembly, and so there was a great exchange of letters between the two.
Katalin Bánffy also corresponded in Latin and German with King of Hungary Maximilian II, the widowed Queen Mary, and Catherine de Medici.
As her marriage remained childless, Katalin took it on herself to raise the children of other families in the courts of Güssing and Rechnitz.
If a girl was preparing for marriage, Katalin planned the wedding feast.
