Daniel Parker (January 29, 1781 – December 3, 1844) was an early American leader in the Primitive Baptist Church in the Southern United States and the founder of numerous churches including Pilgrim Primitive Baptist Church at Elkhart, Texas, the location of the Parker family cemetery. As an elder, Parker led a group who separated from that church and formed the Two-Seed-in-the-Spirit Predestinarian Baptists. Parker is one of the earliest documented proponents of the doctrine of Serpent Seed among Protestant Christianity.
