We construct a D-brane soliton, a composite topological soliton sharing some properties with a D-brane, in a Skyrme model in dimensions, in which Skyrmions are strings ending on a domain wall. We further generalize this D-brane soliton to diverse dimensions. A string, carrying the topological charge, ends on a domain wall in an model with higher-derivative terms in dimensions.
