Abstract Single differential 2-jet and 3-jet cross sections as a function of jet transverse momentum and invariant mass are measured in photoproduction using the H1 detector at HERA. The data sample comprises all available $e^+p$ data collected from 1994-97. Jets are found using the longitudinal boost-invariant \kt algorithm run in the laboratory frame with a minimum transverse momentum of the highest transverse momentum jet of greater than $25~\gev$. When the cross sections for two and three jet production are compared with QCD predictions, no significant deviations from expectation are found.
