Call of Cthulhu Keeper's Screen is a 1985 role-playing game supplement for Call of Cthulhu published by Chaosium.

Call of Cthulhu Keeper's Screen is a three-panel cardstock gamemaster's screen with tables to help the gamemaster keep track of ranged and melee weapons, monsters, spells, rules for sanity loss and fictional Mythos books.

[1] The Keeper's Screen features tables for combat, magic, and skills, with third edition Call of Cthulhu rules data; the second version of the screen also includes the "knock-out" rule, and weapons data from the supplements Cthulhu Now and Cthulhu by Gaslight.

[2] Guy Hail reviewed Call of Cthulhu Keeper's Screen in Space Gamer/Fantasy Gamer No.

[1] Hail commented that "The new tables will settle some disputes about thrown weapons, and a Keeper should have a cthuloid screen to hide his secrets from nosy investigators, but Chaosium should have used this opportunity to cumulate Call of Cthulhu's monsters and spells in a single supplement.
