A special election was held on May 21, 1996 to fill the vacancy created when incumbent Ron Wyden resigned effective February 5, 1996 after winning a special election to the United States Senate. The winner of the election, Earl Blumenauer, served the remainder of Wyden's two-year term.

Before the 2002 redistricting, the whole of Multnomah County was included in the district; it lost southwest Portland to the 1st and 5th districts, but it gained most of its current portion of Clackamas County.^[6][7]
