The Atlantic blue crab Callinectes sapidus is a portunid native to the western Atlantic, from New England to Uruguay. The species was introduced in Europe in 1901 and in recent years it has become invasive; additionally, a significant northward expansion has been emphasized also in its native range. Here we present a harmonized global compilation of occurrences of the Atlantic blue crab Callinectes sapidus from native and non-native distribution ranges. Data are derived from online databases (GBIF, BISON, OBIS, and iNaturalist) as well as from peer-reviewed literature and unpublished sources gathered from personal communications and from available-on-request databases either directly maintained by the Hellenic Centre for Marine Research (HCMR; https://www.hcmr.gr), or connected with the HCMR, such as the Ellenic Network on Aquatic Invasive Species (ELNAIS; https://elnais.hcmr.gr). The dataset consists of 25,930 geo-referenced occurrences, 25,319 from native and 611 from non-native ranges, recorded in 54 countries. A technical validation procedure based on dichotomous keys was used to flag in-land records and those located at a distance < 2Km from the coastline. Similarly, a flagging system identified occurrences outside the known distribution of the species, or associated with unsuccessful introductions. The dataset is complemented by a complete list of literature sources, including permanent identifiers (bibliographic Citation DOI) if available, and a list of notes related with outliers and unsuccessful intentional introductions outside the native range numbered according to the flags included in the dataset.

Abstract
The Atlantic blue crab Callinectes sapidus is a portunid native to the western Atlantic, from New England to Uruguay. The species was introduced in Europe in 1901 and in recent years it has become invasive; additionally, a significant northward expansion has been emphasized also in its native range. Here we present a harmonized global compilation of occurrences of the Atlantic blue crab Callinectes sapidus from native and non-native distribution ranges. Data are derived from online databases (GBIF, BISON, OBIS, and iNaturalist) as well as from peer-reviewed literature and unpublished sources gathered from personal communications and from available-on-request databases either directly maintained by the Hellenic Centre for Marine Research (HCMR; https://www.hcmr.gr), or connected with the HCMR, such as the Ellenic Network on Aquatic Invasive Species (ELNAIS; https://elnais.hcmr.gr). The dataset consists of 25,930 geo-referenced occurrences, 25,319 from native and 611 from non-native ranges, recorded in 54 countries. A technical validation procedure based on dichotomous keys was used to flag in-land records and those located at a distance < 2Km from the coastline. Similarly, a flagging system identified occurrences outside the known distribution of the species, or associated with unsuccessful introductions.
