The 58th Scripps National Spelling Bee was held in Washington, D.C. at the Capital Hilton on June 5–6, 1985, sponsored by the E.W. Scripps Company.
The winner was 13-year-old eighth-grader Balu Natarajan of Bolingbrook, Illinois, in his third appearance at the Bee (he finished 45th in 1983 and 63rd in 1984), the first winner from the Chicago area. He spelled "milieu" for the win. Second place went to 13-year-old Kate Lingley of Dover-Foxcroft, Maine, who missed "farrago". Another 13-year-old, Tanya Solomon of Kansas City, Missouri, took third, missing "syllepsis".
168 spellers competed in the Bee, 17 more than competed the previous year.
