Grenora is a city in Williams County, North Dakota, United States. The population was 221 at the 2020 census.
Grenora was founded in July 1916 at the terminus of a Great Northern Railway branch line that began in Stanley. The name is a portmanteau of letters in the railway's name: GREat NOrthern RAilway. The tracks were in place until 2002, when Great Northern successor BNSF Railway filed for abandonment.
The city's motto is, "Friendliness lives here – you're only a stranger once." The city is home to a senior citizen's center, credit union, gas station, grain elevator, restaurant, bar, apartment buildings, and community-built low-income housing. There are also two churches: the St. Olaf Lutheran Church (ELCA), and St. Boniface Catholic Church.
