{{Short description|River in Wiltshire, England}} {{Use dmy dates|date=November 2017}} {{Use British English|date=November 2017}} thumb|upright|Swill Brook '''Swill Brook''' is the name of a number of streams in England, the most notable of which is the '''Swill Brook''' in Wiltshire. This stream flows for some 10&nbsp;km or 6 miles in a generally easterly direction from its sources near the village of Crudwell to its confluence with the River Thames near Ashton Keynes. Its chief claim to fame is that the Thames is actually a tributary of the Swill Brook, as the latter is considerably larger than the Thames where they meet.<ref>{{cite web |url=http://nora.nerc.ac.uk/15409/1/N015409CR.pdf |title=Sandpool Farm Flood Study (Table 4.1)|publisher=Institute of Hydrology, for Natural Environment Research Council|accessdate=6 February 2017}}</ref>
