SOHO彗星（ソーホー彗星、ソーホーすいせい）は、欧州宇宙機関 (ESA) とアメリカ航空宇宙局 (NASA) が共同で打ち上げ運用している太陽探査機SOHOによって発見された彗星である。狭義にはSOHOに搭載された観測機器のうち、LASCO（広角分光コロナグラフ）で発見された物のみを指し、近日点が太陽に極めて近い彗星（サングレーザー）である。SWAN（太陽風観測カメラ）で発見されたものはSOHO彗星に含められることもあるが、通常はSWAN彗星（スワンすいせい）と呼ばれる。SWAN彗星はサングレーザーではなく、地球上からも観測できる。2007年9月までに1290個のSOHO彗星と8個のSWAN彗星が発見されており、これは命名された全彗星の40%を超える。

SOHO周期彗星 通常、周期彗星は2回目の回帰が確認された段階で番号登録されるが、SOHO彗星に関しては似た軌道を持つ彗星が多くLASCOの観測精度も悪いため、4回目の回帰まで待つことになっている。
