The KM3NeT/ORCA is a next-generation neutrino detector currently under construction in the Mediterranean Sea. There are currently 6 Detection Units deployed, and in the past year the detector has been steadily taking data. Here the first neutrino oscillation measurement is presented using data taken with the ORCA detector 6 Detection Units, containing 354.6 days of exposure. Selection criteria are discussed, followed by a neutrino oscillation analysis. In the analysis it is found that oscillations are preferred with a confidence level of 5.9 σ over “no oscillations”. Likelihood scans of the Δm312 and sin2 θ23 parameter also show a strong exclusion of the no oscillation hypothesis. The sensitivity contour in (sin2 θ23, Δm312) is presented, showing results that are approaching to being being competitive with other experiments [1]
