Sapulpa is a city in Creek and Tulsa counties in the U.S. state of Oklahoma. The population was 20,544 at the 2010 United States census, compared to 19,166 at the 2000 census. As of 2013 the estimated population was 20,836. It is the county seat of Creek County.
The town was named after the area's first permanent settler, a full-blood Lower Creek Indian named Sapulpa, of the Kasihta Tribe, from Osocheetown, Alabama. About 1850, he established a trading post near the meeting of Polecat and Rock creeks (about one mile (1.6 km) southeast of present-day downtown Sapulpa). When the Atlantic and Pacific Railroad (later known as the Frisco) built a spur to this area in 1886, it was known as Sapulpa Station. The Sapulpa post office was chartered July 1, 1889. The town was incorporated March 31, 1898.
After Oklahoma became a state, each county held an election to determine the location of the county seat. Sapulpa competed with Bristow for county seat of Creek County. After five years of contested elections and court suits, the question was settled by the Oklahoma Supreme Court on August 1, 1913. Sapulpa was ruled the winner. The county courthouse was completed in 1914, replacing an earlier structure built in 1902.
The area around Sapulpa mainly produced walnuts when the town was founded. In 1898, the Sapulpa Pressed Brick was established, followed in a few years by the Sapulpa Brick Company. This began the clay products industry. The Frisco built a railyard in Sapulpa and by 1900 designated Sapulpa as the location of an overhaul base for its rolling stock. The founding of Premium Glass Company in 1912 marked Sapulpa's entry to glass manufacturing. Premium Glass was absorbed into Liberty Glass Company in 1918. Other glass producers in the city were Bartlett-Collins Glass Company, Schram Glass Company, and Sunflower Glass Company. According to the Encyclopedia of Oklahoma History, Sapulpa became known as "The Crystal City of the Southwest". Sapulpa is also the home of Frankoma Pottery.
Sapulpa is located in the northeast corner of Creek County at  A small portion of the city extends north into Tulsa County and was annexed into the city in 2004. Downtown Tulsa is 14 miles (23 km) to the northeast via Interstate 44. The Creek Turnpike (State Highway 364) branches east from I-44 in northeastern Sapulpa and provides a southern and eastern bypass of Tulsa.(36.003536, -96.104822).
In January 2018, the Sapulpa City Council voted to approve the annexation of approximately 300 acres of land in West Tulsa. The land is bordered to the north by 51st street, to the south by Southwest Blvd, and to the west by 65th West Avenue. Originally, this annexation included the future site of the interchange of the Gilcrease Expressway and I-44. However, the city has now planned to de-anex this area back to the city of Tulsa.

The Sapulpa Daily Herald gained national media attention in early November 2008 for not reporting the election of Barack Obama as president, reporting only that John McCain had won among the voters of Creek County. Critics charged that the omission related to racism, as Obama's victory as the first African American elected president was an historic event. The newspaper maintains that it only covers local news events. The newspaper had covered every single presidential victory prior to the Obama victory.
