A search for high-mass dimuon resonance production in association with one ormore b quark jets is presented. The study uses proton-proton collision datacollected with the CMS detector at the LHC corresponding to an integratedluminosity of 138 fb$^{-1}$ at a center-of-mass energy of 13 TeV.Model-independent limits are derived on the number of signal events withexactly one or more than one b quark jet. Results are also interpreted in alepton-flavor-universal model with Z$'$ boson couplings to a bb quark pair($g_\mathrm{b}$), an sb quark pair ($g_\mathrm{b}\delta_\mathrm{bs}$), and anysame-flavor charged lepton ($g_\ell$) or neutrino pair ($g_\nu$), with$\left|g_{\nu}\right| = \left|g_\ell\right|$. For a Z$'$ boson with a mass$m_{\mathrm{Z}'}$ = 350 GeV (2 TeV) and $\left|\delta_\mathrm{bs}\right|$ $\lt$0.25, the majority of the parameter space with 0.0057 $\lt$$\left|g_\ell\right|$ $\lt$ 0.35 (0.25 $\lt$ $\left|g_\ell\right|$ $\lt$ 0.43)and 0.0079 $\lt$ $\left|g_\mathrm{b}\right|$ $\lt$ 0.46 (0.34 $\lt$$\left|g_\mathrm{b}\right|$ $\lt$ 0.57) is excluded at 95% confidence level.Finally, constraints are set on a Z$'$ model with parameters consistent withlow-energy b $\to$ s$\ell\ell$ measurements. In this scenario, most of theallowed parameter space is excluded for a Z$'$ boson with 350 $\ltm_{\mathrm{Z}'}$ $\lt$ 500 GeV, while the constraints are less stringent forhigher $m_{\mathrm{Z}'}$ hypotheses. This is the first dedicated search at theLHC for a high-mass dimuon resonance produced in association with multiple bquark jets, and the constraints obtained on models with this signature are themost stringent to date.
