84P/Giclas is a Jupiter-family comet with a 6.69-year orbit around the Sun. It is the only comet discovered by American astronomer, Henry L. Giclas.
== Observational history == === 1931 apparition === It was announced in 1995 that Clyde W. Tombaugh had observed a previously unknown comet for three nights in September 1931. Designated as D/1931 R1, it was later confirmed to be an earlier apparition of 84P/Giclas upon reconstructing its orbit using non-gravitational accelerations in a 1996 study by .
