The Siøsund Bridge ({{langx|da|Siøsundbroen}}) is a road bridge that connects the Danish islands of Tåsinge and Siø. It crosses Siøsund, a shallow strait that allowed much of the link to be built as a causeway, the Siø Causeway or Siø Dam ({{langx|da|Siødæmningen}}).{{cite magazine |last=Kongsløv |first=Ove |date=1961-10-02 |title=Nye tider i øhavet |url=https://www.e-pages.dk/ingarkiv/5326/?page= |language=da |magazine=Polyteknikeren |volume=27 |issue=8 |pages=9–13 |access-date=2018-01-14 }}

The bridge is a low box girder bridge that does not allow the passage of ships. It consists of 20 identical spans, each {{convert|27|m|ft|0}} long, and was the first bridge in Denmark to be built from prefabricated concrete box girders. The road deck is {{convert|7.0|m|ft|0}} wide, with a {{convert|2.5|m|ft|0|abbr=on}} pavement on either side.

The bridge and causeway are part of route 9 which also connects Tåsinge to Funen via the Svendborgsund Bridge and Siø to Langeland via the Langeland Bridge.
