Sueo Oe (?? ??, Oe Sueo, August 2, 1914 – December 24, 1941) was a Japanese athlete who competed mainly in the pole vault.
He won a bronze medal at the 1936 Summer Olympics held in Berlin, Germany, tying with his teammate Shuhei Nishida.
When the two declined to compete against each other to decide a winner, Nishida was arbitrarily awarded the silver.
The competition was featured in a scene in the documentary Olympia, filmed by Leni Riefenstahl.
On their return to Japan, Nishida and Oe had their Olympic medals cut in half, and had a jeweler splice together two new “friendship medals”, half in bronze and half in silver.
In 1937 Oe set a national record at 4 m 35 cm that stood for 21 years.
In 1939 he joined the Imperial Japanese Army and was killed in action in the Battle of Wake Island on December 24, 1941.
