Knob Noster was platted in 1856. A town in the eastern part of Washington Township, laid out in 1856 by William A. Wortham, and incorporated by act of legislature December 14, 1859. All authorities agree that the name is connected with the prominent mound or knob that stand isolated on the prairie near the town. The second part of the name is said to have been suggested by a school teacher, but its origin is uncertain. Eaton derives it from the Latin, interpreting the whole name as a barbarous mixture signifying "Our Knobs," an etymology which seems unlikely. Further light on the source of the name is needed. The town was removed to its present site when the Pacific Railroad was built. A post office has been in operation in Knob Noster since 1846.
