<jats:title>Abstract</jats:title> <jats:p>We report a search for astronomical neutrinos in the energy region from several GeV to TeV in the direction of the blazar TXS 0506+056 using the Super-Kamiokande detector following the detection of a 100 TeV neutrinos from the same location by the IceCube collaboration. Using Super-Kamiokande neutrino data across several data samples observed from 1996 April to 2018 February we have searched for both a total excess above known backgrounds across the entire period as well as localized excesses on smaller timescales in that interval. No significant excess nor significant variation in the observed event rate are found in the blazar direction. Upper limits are placed on the electron- and muon-neutrino fluxes at the 90% confidence level as 6.0 × 10<jats:sup>−7</jats:sup> and 4.5 × 10<jats:sup>−7</jats:sup>–9.3 × 10<jats:sup>−10</jats:sup> [erg cm<jats:sup>−2</jats:sup> s<jats:sup>−1</jats:sup>], respectively.</jats:p>
