<jats:title>A<jats:sc>bstract</jats:sc></jats:title><jats:p>Coherent production of<jats:italic>J/ψ</jats:italic>mesons is studied in ultraperipheral lead-lead collisions at a nucleon-nucleon centre-of-mass energy of 5 TeV, using a data sample collected by the LHCb experiment corresponding to an integrated luminosity of about 10 μb<jats:sup>−1</jats:sup>. The<jats:italic>J/ψ</jats:italic>mesons are reconstructed in the dimuon final state and are required to have transverse momentum below 1 GeV. The cross-section within the rapidity range of 2<jats:italic>.</jats:italic>0<jats:italic>&lt; y &lt;</jats:italic>4<jats:italic>.</jats:italic>5 is measured to be 4<jats:italic>.</jats:italic>45 ± 0<jats:italic>.</jats:italic>24 ± 0<jats:italic>.</jats:italic>18 ± 0<jats:italic>.</jats:italic>58 mb, where the first uncertainty is statistical, the second systematic and the third originates from the luminosity determination. The cross-section is also measured in<jats:italic>J/ψ</jats:italic>rapidity intervals. The results are compared to predictions from phenomenological models.</jats:p>
