Jeffrey Kaplan is an American video game designer and former vice president of Blizzard Entertainment, a position he held until he left the company in 2021.

[6] Kaplan's initial work at Blizzard was helping with quality assurance for Warcraft III: Reign of Chaos in the weeks prior to its release.

[6] After Warcraft III shipped, he joined with the WoW team as one of the first two quest designers along with Pat Nagle, and worked closely with the game's creative director Chris Metzen.

[7] In February 2009, Kaplan announced that he was stepping down as game director for WoW to switch his role at Blizzard to a new, unannounced MMO, which later was revealed as Titan.

[3] Titan was considered an ambitious project, designed as a class-based first-person shooter, but had a prolonged and struggling development period along with gameplay that Kaplan called "very cluttered and confused".

Kaplan and Metzen led this team to take some of the gameplay and creative elements of Titan and created a team-based shooter, which became Overwatch.

[15] A tribute to Kaplan was planned to be included in Overwatch 2 by the name of a background storefront "Jephs Corner Pizza" in the New York City map.
