A hot melt adhesive composition includes (A) 10-95 wt % of a random or homogeneous propylene-based interpolymer having: (i) a comonomer content of at least one of C2 and C4-10 a-olefin of 7 wt % to 49 wt % based on the total weight of the propylene-based interpolymer, (ii) an MWD of 4 or less, (iii) a density of 0.90 g/cc or less, and (iv) a Brookfield viscosity of less than 50,000 centipoise, (B) 1-60 wt % of a crystalline block composite comprising: (1) a crystalline ethylene based polymer; (2) a crystalline alpha-olefin based polymer derived from at least one of a C3-10 a-olefin; and (3) a block copolymer comprising 10-90 wt % of a crystalline ethylene block comprising greater than 90 mol % units derived from ethylene and comprising 10-90 wt % of a crystalline alpha-olefin block comprising greater than 90 mol % units derived from at least one of a C3-10 a-olefin, (C) Optionally, from greater than zero to 70 wt % tackifier, and (D) Optionally, from greater than zero to 40 wt % of at least one selected from the group of a wax and an oil.
