We report the synthesis and characterization of K$_{1-x}$CrTe$_2$ single crystals ($x \\approx 0.3$), which crystallize in the $Cm$ space group with trigonal prismatic K$^+$ coordination, unlike the octahedral environments of more stoichiometric ACrX$_2$ compounds. Magnetization measurements show a sharp ferromagnetic transition at $T_{\\rm C}=117$ K and in-plane magnetic anisotropy, supported by density functional theory.
