'''''Neocalanus''''' is a genus of marine copepods.<ref name=WoRMS/> They are a dominant component of the open water ecosystems of the northern Pacific Ocean.<ref name="Conover 1988"/> ''Neocalanus'' are large copepods, reaching body lengths (i.e., prosome length) of more than {{convert|8|mm|abbr=on}} in ''Neocalanus plumchrus''.<ref name="Kobari et al. 2003"/>

==Species== There are six species:<ref name=WoRMS/> {{columns-list|colwidth=25em| * ''Neocalanus cristatus'' (Krøyer, 1848) * ''Neocalanus flemingeri'' Miller, 1988 * ''Neocalanus gracilis'' (Dana, 1852) * ''Neocalanus plumchrus'' (Marukawa, 1921) * ''Neocalanus robustior'' (Giesbrecht, 1888) * ''Neocalanus tonsus'' (Brady, 1883) }}

==Life cycle== ===''Neocalanus flemingeri'' === ''Neocalanus flemingeri'' is predominantly annual, with a significant fraction of biennials in some areas. The largest females reach prosome length of about {{convert|5|mm|abbr=on}}; males are smaller.<ref name="Kobari and Ikeda 2001"/>

==Trophic interactions== ''Neocalanus'' are important food items for many predators, such as North Pacific right whale<ref name=NMFS2006/> and least auklet.<ref name="Dorresteijn et al. 2012"/>
