Abstract: We present the first measurement of the variation of the high-energy neutrino flux along the Galactic plane using 10 years of neutrino-induced particle-shower data from the IceCube Neutrino Observatory. In this Letter, we fit both the neutrino flux normalization and the spectral index, in multiple regions along the plane, independent of model expectations. The neutrino flux per solid angle in the inner Galactic region ($\vert l\vert< 30^{\circ}, \vert b\vert < 8^{\circ}$) is approximately five times higher than in the outer Galactic plane ($\vert l\vert>60^{\circ}, \vert b\vert < 8^{\circ}$) at $E_ν=5\mathrm{TeV}$. The spectral indices in the inner and outer region are $γ=2.76^{+0.18}_{-0.15}$ and $γ= 3.13^{+0.57}_{-0.37}$, respectively. Additionally, we compare the same region of Galactic emission measured in $\mathrm{TeV}$ gamma rays by LHAASO ($15^{\circ}
