Caroline Bayard Stevens Wittpenn (November 21, 1859 – December 4, 1932) was a social reformer and welfare worker from Hoboken, New Jersey.
She directed several welfare organizations in New Jersey in the early twentieth century, and she worked within the state's government to promote welfare-related causes.
She also campaigned to establish Clinton Farms Reformatory, the first dedicated women's prison in New Jersey, and led its board of managers for nearly twenty years.
Her work with impoverished women and girls inspired her to pursue welfare reform, and she began movements to overhaul the State Charities Aid Association and provide better living conditions for children in almshouses.
In keeping with her Episcopal faith and common practices of the time, she waited for her bishop to presume her first husband dead before remarrying.
