Lenard "Len" Lakofka (1944 - 2020) was an American writer of material for the fantasy role-playing game Dungeons & Dragons. Although never a formal TSR staff member, the company that published Dungeons & Dragons, he was an influential voice in the development of the game. He was one of the playtesters of the game as it was being developed, an editor of early manuscripts, wrote a widely-read monthly D&D magazine column and two official D&D adventures, and had his home campaign setting of the Lendore Isles incorporated into the World of Greyhawk Fantasy Game Setting.
