Abstract In this study, we investigate the Barrow holographic dark energy (BHDE) model with the Granda-Oliveros(G-O) infrared (IR) cut-off in the presence of neutrino masses, utilizing the latest observational data to address the Hubble tension. The GO cut-off is defined as $L_{IR}=(\alpha H^2 + \beta \dot{H})^{-1/2}$. We place constraints on the total neutrino mass ∑mν using data from Type Ia supernovae (SN) Pantheon, cosmic chronometers (CC), Cosmic Microwave Background (CMB), Baryon Acoustic Oscillation (BAO) datasets, and Planck Lensing. Specifically, the comprehensive CMB+BAO+CC+Pantheon dataset provides a total neutrino mass of 0.118 eV. The parameters for the Barrow-GO model are determined to be $\Delta = 0.0055^{+0.0086}_{-0.0086}$, $\alpha = 0.997^{+0.060}_{-0.060}$, and $\beta = 0.598^{+0.080}_{-0.080}$, showing good agreement with previous studies. One of the key findings of this study is the model’s ability to alleviate the Hubble tension, as evidenced by the comparison of H0 measurements. Specifically, the tension value for the combination of dataset (CMB+BAO+CC+Pantheon+Lensing) is 1.5σ with the Planck 2018 and 1.4σ with R22. These results underscore the importance of multi-dataset integration in refining constraints on neutrino properties and highlight the model’s efficacy in probing fundamental aspects of neutrino physics. Our results demonstrate that the BHDE model with the GO cut-off can effectively address the Hubble tension, offering a coherent framework that reconciles local and cosmological measurements of the Hubble constant.
