Kathleen "Kat" Kinkade (December 6, 1930 – July 3, 2008) was one of the eight co-founders of Twin Oaks, an intentional community in Virginia inspired by the behaviorist utopia depicted in B.F. Skinner's book Walden Two.

Her daughter, Josie, was also a member of Twin Oaks as an adolescent and young adult.

At age 70, she moved into a small house fifteen miles away in the town of Mineral.

Twin Oaks took her in to provide end-of-life care, an exception made in honor of her unique contribution to the Community.

Kinkade died of breast cancer complications on July 3, 2008, aged 77, shortly after Twin Oaks' 41st anniversary.
