Theodore Sturgeon [fonetski: Teodor Sterdžen] (26.2. 1918. – 8.5. 1985.) je bio američki pisac naučne fantastike koji je najpoznatiji po svojim kratkim pričama i kao osoba koja je izmislila prvu direktivu koja govori o nemešanju u poslove nerazvijenih planeta u Star Treku. Također on se navodno nalazio s svojim kolegom SF piscem L. Ron Hubbardom, kada je on povikao:

"Mi gubimo vreme s naučnom fantastikom. Ako želiš doći do pravog novca moraš stvorit religiju"

Nakon čega je Hubbard stvorio Scientologiju.
