<jats:title>Abstract</jats:title><jats:p>We assessed the prevalence of life history variation across four of the five native amphidromous Hawai'ian gobioids to determine whether some or all exhibit evidence of partial migration. Analysis of otolith Sr.: Ca concentrations affirmed that all are amphidromous and revealed evidence of partial migration in three of the four species. We found that 25% of <jats:styled-content style="fixed-case"><jats:italic>Lentipes concolor</jats:italic></jats:styled-content> (<jats:italic>n =</jats:italic> 8), 40% of <jats:styled-content style="fixed-case"><jats:italic>Eleotris sandwicensis</jats:italic></jats:styled-content> (<jats:italic>n =</jats:italic> 20) and 29% of <jats:styled-content style="fixed-case"><jats:italic>Stenogobius hawaiiensis</jats:italic></jats:styled-content> (<jats:italic>n =</jats:italic> 24) did not exhibit a migratory life‐history. In contrast, all individuals of <jats:styled-content style="fixed-case"><jats:italic>Sicyopterus stimpsoni</jats:italic></jats:styled-content> (<jats:italic>n =</jats:italic> 55) included in the study went to sea as larvae. <jats:styled-content style="fixed-case"><jats:italic>Lentipes concolor</jats:italic></jats:styled-content> exhibited the shortest mean larval duration (LD) at 87 days, successively followed by <jats:styled-content style="fixed-case"><jats:italic>E. sandwicensis</jats:italic></jats:styled-content> (mean LD = 102 days), <jats:styled-content style="fixed-case"><jats:italic>S. hawaiiensis</jats:italic></jats:styled-content> (mean LD = 114 days) and <jats:styled-content style="fixed-case"><jats:italic>S. stimpsoni</jats:italic></jats:styled-content> (mean LD = 120 days). These findings offer a fresh perspective on migratory life histories that can help improve efforts to conserve and protect all of these and other at‐risk amphidromous species that are subject to escalating anthropogenic pressures in both freshwater and marine environments.</jats:p>
