Roaring Brook I Site and Roaring Brook II Site are two Middle to Late Woodland Period archeological sites in East Haddam, Connecticut, that were listed on the National Register of Historic Places in 1987. The Roaring Brook cultural phase, associated with multiple sites in the vicinity, is dated to 2000–1250 BP (AD 1–750). Both National Register listings are for areas of less than one acre. Surveys conducted during the 1980s located these, as well as other sites in the lower Connecticut Valley.
