Bill Henrickson is the protagonist father in a polygamist family in the fictional HBO series Big Love, portrayed by Bill Paxton. He is married to three wives, Barb Henrickson, Nicki Grant and Margene Henrickson. From these three women he has fathered seven children.

Bill was born May 17, 1958 to Frank Harlow and Lois Henrickson at the Juniper Creek compound, a fictitious community that practices fundamentalist Mormon principles including polygamy.

Bill spent most of his childhood in this community with his brother Joey and sister Margaret, but was thrown out of the compound by his father on instructions from Roman, who found Bill too much like his grandfather. While attending college he met his first wife Barbara, who was a devout Mormon. Upon marrying her, he abandoned the principles of fundamentalist Mormonism and polygamy, and became a member of The Church of Jesus Christ of Latter-day Saints.

Soon after Tancy's birth, however, Barbara Henrickson was diagnosed with uterine cancer, from which she was expected to die. During her illness, Bill revisited the compound in which he grew up and there he met Nicolette Grant, the daughter of the Juniper Creek prophet Roman Grant. Nicolette helped to comfort Barbara while she was sick, and it was decided that when Barbara died that Nicolette was to marry Bill and raise her children. Barbara, however, recovered from her illness, and instead of abandoning Nicolette, Bill decided to return to the principle of polygamy and take her as his second wife. Nicki is mother to two of Bill's children, Raymond and Wayne.

Bill owns a hardware store, Henrickson Home Plus.
