William Coates (June 2, 1889? or 1911? – February 23, 2004) of Maryland was an unverified claimant as a supercentenarian whose actual age was subsequently disputed. Following his death, news reports said Coates was believed to have been the oldest man in the United States at 114 years old, based upon his nursing home records. The reports noted there was no birth certificate.
