ABSTRACT=<p>Groundnut or peanut (<italic>Arachis hypogaea</italic>) is a legume crop. Its seeds are rich in protein and oil. Aldehyde dehydrogenase (ALDH, EC: 1.2.1.3) is an important enzyme involved in detoxification of aldehyde and cellular reactive oxygen species, as well as in attenuation of lipid peroxidation-meditated cellular toxicity under stress conditions. However, few studies have been identified and analyzed about ALDH members in <italic>Arachis hypogaea</italic>. In the present study, 71 members of the ALDH superfamily (AhALDH) were identified using the reference genome obtained from the Phytozome database. A systematic analysis of the evolutionary relationship, motif, gene structure, <italic>cis</italic>-acting elements, collinearity, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment, and expression patterns was conducted to understand the structure and function of <italic>AhALDH</italic>s. <italic>AhALDH</italic>s exhibited tissue-specific expression, and quantitative real-time PCR identified significant differences in the expression levels of <italic>AhALDH</italic> members under saline-alkali stress. The results revealed that some <italic>AhALDHs</italic> members could be involved in response to abiotic stress. Our findings on <italic>AhALDHs</italic> provide insights for further study.</p>
