Johan Georg Ræder (21 March 1814 – 3 January 1898) was a Norwegian military officer, railway pioneer and politician.
He graduated from the Military College in 1837, and was then assigned with the Engineering Brigade (Norwegian: Ingeniørbrigaden).
At the crowning ceremony of King Oscar II in the Nidaros Cathedral in 1873 he carried the Royal Sword.
A painting by Knud Bergslien from 1874 depicting this ceremony is located at the Royal Palace in Oslo.
He was a member of several public commissions, and wrote many articles for the magazine Norsk Militært Tidsskrift.
