August "Ago" Neo (12 February 1908 – 19 August 1982) was an Estonian wrestler who won two medals at the 1936 Summer Olympics: a silver medal in the freestyle wrestling and a bronze in Greco-Roman wrestling.

His achievements were underscored by teammate Kristjan Palusalu, who won two gold medals in wrestling at the same games.

Neo also won five medals in both wrestling styles at the European championships in 1934–1939.

He missed the 1932 Olympics because Estonia did not send an ample team to Los Angeles due to the Great Depression.

Neo was first buried at Stockholm, but in 1998 reburied at the Metsakalmistu cemetery in Tallinn, Estonia.
