State Route 821 (SR 821) is a north–south state highway in the southeastern portion of the U.S. state of Ohio. A state-maintained section of the old US 21, its southern terminus is at SR 60 approximately {{convert|2|mi}} north of Marietta, and its northern terminus is at I-77 in Byesville, along with the eastern terminus of SR 209. The route is entirely undivided surface road, and is much less direct than the newer I-77 which supplanted it as a through route. As the interstate was being built, the designation of US 21 was moved to the freeway before Ohio wholly decommissioned the now-superfluous U.S. route. SR 821 was designated about two years after US 21 was moved onto I-77 in southeastern Ohio.

Along its path, SR 821 passes through central portions of Washington County and Noble County, and into the southern part of Guernsey County. No segment of the route is included as a part of the National Highway System (NHS). The NHS is a network of highways identified as being most important for the economy, mobility and defense of the nation.{{cite map | title=National Highway System: Ohio | date=December 2003 | publisher=Federal Highway Administration | url=http://www.fhwa.dot.gov/planning/nhs/maps/oh/oh_Ohio.pdf | archive-url=https://web.archive.org/web/20081016165827/http://www.fhwa.dot.gov/planning/nhs/maps/oh/oh_Ohio.pdf | url-status=dead | archive-date=October 16, 2008 | format=PDF|access-date=2011-09-22}}

History
SR 821 was created in 1971. The designation was applied to what was the former routing of US 21 between Marietta and Byesville, prior to the completion of I-77 through the area by 1969. At the time, when the US 21 designation was removed from Ohio in favor of I-77, this stretch of roadway was removed from the state highway system. However, by 1971, it was introduced back into the system, and was given the designation of SR 821, based on its routing along the old path of US 21.{{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1969a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1969 |cartography=ODOH |access-date=2011-09-22}}{{cite map |title=Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1971a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1971 |cartography=ODOH |access-date=2011-09-22}}{{cite map |title=Official Ohio Highway Map |url=http://www.dot.state.oh.us/Divisions/TransSysDev/Innovation/prod_services/Documents/StateMaps/otm1967a.sid |format=MrSID |publisher=Ohio Department of Highways |date=1967 |cartography=ODOH |access-date=2011-09-22}}
