In this data paper, we describe environmental DNA ( eDNA ) cytochrome c oxidase ( COI ) amplicon sequence data from New York City’s Bronx River Estuary. As urban systems continue to expand, describing and monitoring their biodiversity is increasingly important for sustainability. Once polluted and overexploited, New York City’s Bronx River Estuary is undergoing revitalization and restoration. To investigate and characterize the area’s diversity, we collected and sequenced river sediment and surface water samples from Hunts Point Riverside and Soundview Parks (n total  = 48; n sediment  = 25; n water  = 23).  COI  analysis using universal primers mlCOIintF and jgHCO2198 detected 27,328 Amplicon Sequence Variants ( ASVs ) from 7,653,541 sequences, and rarefaction curves reached asymptotes indicating sufficient sampling depth. Of these, eukaryotes represented 9,841ASVs from 3,562,254 sequences. At the study sites over the sampling period, community composition varied by substrate (river sediment versus surface water) and with water temperature, but not pH. The three most common phyla were   Bacillariophyta   (diatoms),   Annelida   (segmented worms), and   Ochrophyta   (e.g. brown and golden algae). Of the eukaryotic  ASVs , we identified 614 (6.2%) to species level, including several dinoflagellates linked to Harmful Algal Blooms such as    Heterocapsa    spp., as well as the invasive amphipod    Grandidierella   japonica   . The analysis detected common bivalves including blue (   Mytilus   edulis   ) and ribbed (   Geukensia   demissa   ) mussels, as well as soft-shell clams (   Mya   arenaria   ), in addition to Eastern oysters (   Crassostrea   virginica   ) that are being reintroduced to the area. Fish species undergoing restoration such as river herring (   Alosa   pseudoharengus   ,    A.   aestivalis   ) failed to be identified, although relatively common fish including Atlantic silversides (   Menidia   menidia   ), menhaden (   Brevoortia   tyrannus   ), striped bass (   Morone   saxatilis   ), and mummichogs (   Fundulus   heteroclitus   ) were found. The data highlight the utility of  eDNA  metabarcoding for analyzing urban estuarine biodiversity and provide a baseline for future work in the area.
