'''Sydfynske Øhav''' eller '''Fynske Øhav''' er betegnelsen for det [[farvand]] syd for [[Fyn]], hvor der ligger mere end 55 [[ø]]er, småøer og [[Holm (ø)|holme]]. Området strækker sig fra [[Helnæs Bugt]] i vest over [[Svanninge Bakker|de Fynske Alper]] ved [[Korinth (Fyn)|Korinth]] og Egebjerg Bakker til området omkring [[Svendborg]] og over vandet til [[Ærø]], [[Tåsinge]] og [[Langeland]] i øst. Det Sydfynske Øhav, der [[geologi]]sk betegnes som et druknet [[moræne]]landskab, strækker sig over et areal på ca. 480 km².
