According to main points of technical solutions, the chain-shaped decorative lamp includes an annular body and a lamp string disposed in the annular body. The annular body includes an upper housing and a lower housing that are detachably connected to each other. A plurality of pairs of limited posts are disposed in the upper housing. Each pair of limited posts forms a clamping gap. A lamp strip on the lamp string is clamped into the clamping gap, so that a bead on the lamp string is fastened into the upper housing. A support column corresponding to each clamping gap is disposed in the lower housing.
