K.C. is a modern initial-based given name and nickname, pronounced "KAY-see." It typically compresses two forenames beginning with K and C, such as Katherine/Keira + Claire/Charlotte or Kevin/Kai + Charles/Christopher, but is also used independently. The form gained visibility in the mid-20th century in the United States through figures like basketball legend K.C. Jones and entertainer KC of KC and the Sunshine Band, and it continues to feel breezy and unisex across English-speaking countries.

As initials, K.C. has no single intrinsic meaning; its significance derives from the expanded names parents choose.
