Abstract: <jats:title>Abstract</jats:title><jats:p>The search for neutrino events in correlation with 42 most intense fast radio bursts (FRBs) has been performed using the Borexino dataset from 05/2007 to 06/2021. We have searched for signals with visible energies above 250 keV within a time window of <jats:inline-formula><jats:alternatives><jats:tex-math>$$\pm \, 1000$$</jats:tex-math><mml:math xmlns:mml=""> <mml:mrow> <mml:mo>±</mml:mo> <mml:mspace /> <mml:mn>1000</mml:mn> </mml:mrow> </mml:math></jats:alternatives></jats:inline-formula> s corresponding to detection time of a particular FRB. We also applied an alternative approach based on searching for specific shapes of neutrino-electron scattering spectra in the full exposure data of the Borexino detector. In particular, two incoming neutrino spectra were considered: the monoenergetic line and the spectrum expected from supernovae. The same spectra were considered for electron antineutrinos detected through inverse beta-decay reaction. No statistically significant excess over the background was observed. As a result, the strongest upper limits on FRB-associated neutrino fluences of all flavors have been obtained in the 0.5–50 MeV neutrino energy range.</jats:p>
