<p>The production of jets associated to bottom quarks is measured for the first time in PbPb collisions at a center-of-mass energy of 2.76 TeV per nucleon pair. Jet spectra are reported in the transverse momentum (<inline-formula><mml:math display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi>p</mml:mi></mml:mrow><mml:mrow><mml:mi mathvariant="normal">T</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math></inline-formula>) range of <inline-formula><mml:math display="inline"><mml:mrow><mml:mn>80</mml:mn><mml:mi>–</mml:mi><mml:mn>250</mml:mn><mml:mtext> </mml:mtext><mml:mtext> </mml:mtext><mml:mi>GeV</mml:mi><mml:mo>/</mml:mo><mml:mi>c</mml:mi></mml:mrow></mml:math></inline-formula>, and within pseudorapidity <inline-formula><mml:math display="inline"><mml:mrow><mml:mo stretchy="false">|</mml:mo><mml:mi>η</mml:mi><mml:mo stretchy="false">|</mml:mo></mml:mrow><mml:mo><</mml:mo><mml:mn>2</mml:mn></mml:math></inline-formula>. The nuclear modification factor (<inline-formula><mml:math display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi>R</mml:mi></mml:mrow><mml:mrow><mml:mi>AA</mml:mi></mml:mrow></mml:msub></mml:mrow></mml:math></inline-formula>) calculated from these spectra shows a strong suppression in the <inline-formula><mml:math display="inline"><mml:mi>b</mml:mi></mml:math></inline-formula>-jet yield in PbPb collisions relative to the yield observed in <inline-formula><mml:math display="inline"><mml:mi>p</mml:mi><mml:mi>p</mml:mi></mml:math></inline-formula> collisions at the same energy. The suppression persists to the largest values of <inline-formula><mml:math display="inline"><mml:msub><mml:mi>p</mml:mi><mml:mi mathvariant="normal">T</mml:mi></mml:msub></mml:math></inline-formula> studied, and is centrality dependent. The <inline-formula><mml:math display="inline"><mml:msub><mml:mi>R</mml:mi><mml:mi>AA</mml:mi></mml:msub></mml:math></inline-formula> is about 0.4 in the most central events, similar to previous observations for inclusive jets. This implies that jet quenching does not have a strong dependence on parton mass and flavor in the jet <inline-formula><mml:math display="inline"><mml:msub><mml:mi>p</mml:mi><mml:mi mathvariant="normal">T</mml:mi></mml:msub></mml:math></inline-formula> range studied.</p>
