We present a georeferenced dataset of freshwater Malacostraca occurrences across continental Chile, compiled from published literature, technical reports, and field studies. The dataset includes 625 occurrence records from 38 species across 4 families, covering a wide latitudinal gradient (~18°S to ~56°S). Freshwater Malacostraca play key ecological roles in aquatic ecosystems, yet their distribution in Chile remains fragmented across diverse sources. This dataset consolidates available records into a standardized and curated format, enabling improved accessibility and reuse. All records were taxonomically validated using authoritative databases and georeferenced to a common coordinate system (WGS84). The dataset is publicly available through an open-access repository and provides a baseline for biodiversity, biogeographic, and ecological research in Chilean inland waters. This dataset represents one of the first consolidated compilations of freshwater Malacostraca occurrences across Chile. It provides a baseline for biodiversity and biogeographic studies across a strong latitudinal gradient. The dataset is useful for ecological modeling, conservation planning, and species distribution analyses. It enables integration with broader biodiversity databases and supports reproducible research.
