We formulate a version of the information paradox in de Sitter spacetime andshow that it is solved by the emergence of entanglement islands in the contextof the DS/dS correspondence; in particular, the entanglement entropy of asubregion obeys a time-dependent Page curve. Our construction works in generalspacetime dimensions and keeps the graviton massless. We interpret theresulting behavior of the entanglement entropy using double holography. Itsuggests that the spatial distribution of microscopic degrees of freedomdepends on descriptions, as in the case of a black hole. In the static(distant) description of de Sitter (black hole) spacetime, these degrees offreedom represent microstates associated with the Gibbons-Hawking(Bekenstein-Hawking) entropy and are localized toward the horizon. On the otherhand, in a global (effective two-sided) description, which is obtained by thequantum analog of analytic continuation and is intrinsically semiclassical,they are distributed uniformly and in a unique semiclassical de Sitter (blackhole) vacuum state.
