is a neighborhood or section in the town of Greenwich in Fairfield County, Connecticut, United States. The town of Greenwich has one political body, but consists of several distinct sections with their own mailing addresses and ZIP codes, such as Byram, Cos Cob, Glenville, Mianus, Old Greenwich, Riverside, and Greenwich (sometimes referred to as Greenwich proper, central, or downtown Greenwich).
St. Paul’s Episcopal Church at 200 Riverside Avenue in Riverside, has held its "Fair for All" since 1942. Money raised goes directly to local charities.
The neighborhood is served by the Riverside Railroad Station on the Metro-North line, although some residents are closer to the Old Greenwich Train Station.
