The first settlement at Portis was made in 1871. In that year a trading post was established at the site.
In 1879, the town was platted with the name of Bethany. The Central Branch Railroad routed through the city and built a station. Later, the railroad was sold to the Missouri Pacific Railroad, becoming the second "Bethany" on their railroad system. To prevent conflicts with Bethany, Missouri, it was decided to change the name of this station. The name was changed to Portis, in honor of the Vice-President of the Missouri Pacific, Thomas Jefferson Portis (born in 1827).
