John Bexley Sedgers (died June 1969) was an Australian businessman.
He spent much of his career in the Territory of Papua and New Guinea, where he served in the Legislative Council from 1951 to 1954.
After around 180 people were airlifted, the remainder (including Sedgers) walked 200 miles to Port Moresby.
In 1951 he was appointed managing director and chairman of the New Guinea branch of Carpenters, moving to Rabaul.
Prior to the elections to the new Legislative Council the same year, he was one of the three European members appointed to the body.
