97P/Metcalf–Brewington is a periodic Jupiter-family comet originally discovered by Joel H. Metcalf in 1906 but subsequently lost. A new observation in 1991 by Howard J. Brewington was matched to the 1906 sighting; the orbit was computed and the comet was observed again on its returns to perihelion in 2001, 2011, and 2022.
