Springfield is a city located in Lane County, Oregon, separated from Eugene, Oregon primarily by the I-5 highway. Springfield was named after a natural spring located in a field or prairie within the current city boundaries. As of the 2000 census, the city had a total population of 52,864. Recent estimations put the population around 60,000.

The first settler who lived where Springfield currently is located was Elias Briggs in 1849, who ran a ferry on the nearby Willamette River. Springfield was incorporated as a city in 1885.

Because of their closeness, the two cities tend to complement each other: Eugene has the University of Oregon, Springfield a number of lumber plants; Eugene is liberal, Springfield somewhat more conservative; Eugene aspires to be upper middle class, whereas Springfield is proudly blue collar.

Many fans of the TV show The Simpsons believe this to be 'the' Springfield of the show, which holds some merit considering the time show creator Matt Groening spent in the area growing up, and other evidence (a popular park, for instance, bears a striking resemblence to the fictional Springfield's town square, the complementing of Springfield and Shelbyville).

Springfield is located at 44°3'11" North, 122°59'28" West (44.053064, -122.991052)GR1.
