The Briggs family first settled the Springfield area, arriving in 1848. The community was incorporated as a city in 1885. The city was named after a natural spring located in a field or prairie within the current city boundaries. For the majority of the 20th century the economy of Springfield was largely dependent on the Oregon timber industry, but since the 1990s the economy has diversified with PeaceHealth now the largest employer in the city. Public education in the city is provided by the Springfield School District.
The first inhabitants to the area were the Kalapuya people. Also sometimes written as Calapooia or Calapooya, the people maintained the valley and their main food sources by controlled burning.
Springfield was settled when Elias and Mary Briggs and their family arrived in 1848.
