The father dropped off his six sons and three daughters aged one to 17 at the Creighton University Medical Center. Their names, including the father's, were not released.
The Nebraska Department of Health and Human Services told CBS News that the nine children were in good health.
The two boys aged 11 and 15 were dropped off at the Immanuel Medical Center.
The parents or caretaker of the 11 children are not legally liable for abandoning them. Nebraska's safe haven law, which took effect in July, was initially intended to prevent abandonment of infants in unsafe places but was revised so hospitals could also serve as safe haven for children and teenagers.
A previous law punishes a parent who abandons an infant and charges them with a misdemeanor.
