Annotation	This paper reports a measurement of D± meson production in jets from proton-proton collisions at a center-of-mass energy of √s=7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb-1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range \|η\|<2.5. D± mesons found in jets are fully reconstructed in the decay chain: D+→D0π+, D0→K-π+, and its charge conjugate. The production rate is found to be N(D±)/N(jet)=0.025±0.001(stat.)±0.004(syst.) for D*± mesons that carry a fraction z of the jet momentum in the range 0.
