NGC 2207 dan IC 2163 adalah pasangan galaksi spiral yang sedang bertabrakan. Galaksi ini berjarak sekitar 144 juta tahun cahaya di rasi bintang Canis Major. Kedua galaksi ditemukan oleh John Herschel pada tahun 1835. Sejauh ini tiga supernova telah diamati di NGC 2207 (SN 1975A, SN 1999ec dan SN 2003H).
Pada November 1999, Hubble Space Telescope mengambil citra kedua galaksi ini. Pada April 2006, Spitzer Space Telescope juga mengambil citra kedua galaksi ini.
