Fluctuations of harmonic flow along pseudorapidity $\eta$, known as flow decorrelations, is an important probe of the initial condition and final state evolution of the quark-gluon plasma. We show that the flow decorrelations are sensitive to the deformations of the colliding nuclei. This sensitivity is revealed clearly by comparing flow decorrelations between collisions of isobars, $^{96}$Zr+$^{96}$Zr and $^{96}$Ru+$^{96}$Ru, which have different deformations. Longitudinal flow decorrelations in heavy-ion collisions is a new tool to probe the structure of colliding nuclei.
