The answer depends on which version of The Office you mean.

  • The original British The Office was created and written by Ricky Gervais and Stephen Merchant.
  • The U.S. version of The Office is an adaptation of the British series, developed for American television by Greg Daniels , with a larger writers’ room that included Mindy Kaling, B.J. Novak, Michael Schur, and Paul Lieberstein among others.

So, in short:

  • British show: Ricky Gervais & Stephen Merchant (creators/writers).
  • U.S. show: Greg Daniels (developer/showrunner) plus a team of writers.
