ORCAE (Online Resource for Community Annotation of Eukaryotes) is a wiki style genome annotation and curation portal for eukaryotic species which offers the community the opportunity and means to improve genome annotations and to keep gene annotations up-to-date.

ORCAE was developed at the Ghent University and published in Nature Methods (manuscript - method). ORCAE-AOCC is a branch that is dedicated to the genomes of African orphan crops (resource - manuscript).
