Timothy James Kask (born January 14, 1949) is an American editor and writer in the role-playing game industry.
Kask became interested in board games in his childhood, and later turned to miniatures wargames.
While attending university after a stint in the US Navy, he was part of a group that playtested an early version of the new role-playing game Dungeons & Dragons (D&D) for game co-designer Gary Gygax.
Gygax hired him as the first employee of TSR, Inc.
in 1975.
After editing some of TSR's early D&D publications, Kask became editor of The Strategic Review, which later became The Dragon, and then Dragon Magazine.
Kask left TSR in 1980 to publish a new magazine, Adventure Gaming, but when that failed, he left the games industry in 1983 and spent some time as a freelance editor and speechwriter before becoming a teacher.
In 2010 he returned to the games industry as one of the co-founders of Eldritch Enterprises.
