The Super-Kamiokande (SK) experiment is a 50 kton water-Cherenkov detector located in Kamioka, Japan. Instrumented with more than 11000 PMTs,
it has been collecting data since 1996 and has been responsible for the very first observation of neutrino oscillations through the analysis
of atmospheric neutrinos. Nowadays, the analysis of SK atmospheric neutrino data keeps providing some of the most precise measurements for
neutrino oscillation parameters such as θ23, the neutrino mass ordering, Δm^2_32, and, to a lesser extent, the δCP phase.

In this presentation, an overview of the most recent atmospheric neutrino oscillation analysis results will be given, as well as, a glimpse
of what is to come, concerning atmospheric neutrinos, in the recently started Gd-doped phase of the detector. This detector upgrade (SuperK-Gd),
provides an efficient neutron tagging via Gd-neutron capture, potentially enhancing the sensitivty of the atmospheric neutrino oscillation analysis.
