Dactylosternum er en slekt av biller som hører til familien vannkjær (Hydrophilidae).
Små til middelsstore (3-5 millimeter), blanke, ovale vannkjær. På farge er de gjerne svarte. Oversiden er fint punktert.
Dactylosternum -artene lever på land, gjerne mellom løvstrø og annet råtnende plantemateriale, for eksempel komposthauger .
Slekten er nært kosmopolittisk , men mangler i de nordligste områdene.
