Discerning between intrinsic and externally-induced properties of galaxies, including their gas kinematics, is a key diagnostic in the field of galaxy evolution. In this work, we present MeerKAT HI spectral line observations of the redshift z $\\sim$ 0.042 galaxy cluster Abell 3408. A total of 64 galaxies are detected in HI in this X-ray-luminous galaxy cluster (L$_{X}$ $\\sim$ 3 $\\times$ 10$^{43}$ ergs s$^{-1}$).
