In 1883, Aaron M. Richey arrived from St. Joseph, Missouri, and settled near the mouth of the Pithlachascotee River. He established a post office in his home on July 9, 1884.
Port Richey was incorporated as a municipality in 1925, in response to the incorporation of New Port Richey the previous year. The name Port Richey is older than the name New Port Richey, as the post offices were established in 1884 and 1915, respectively.
