'''Holosen Tengah''' atau '''Northgrippium''' adalah [[Age (geologi)|sub-kala]] kedua dari [[Kala (geologi)|kala]] [[Holosen]], yang dimulai dari [[Milenium ke-8 SM|8.200 SM]] hingga [[Milenium ke-4 SM|4.200 SM]]. Sub-kala ini ditentukan dengan [[kronostratigrafi]], dan sudah memiliki GSSP (Global Boundary Stratotype Sections and Points).<ref>{{Cite web|title=Geologic TimeScale Foundation - Stratigraphic Information|url=https://timescalefoundation.org/charts/chart.html|website=timescalefoundation.org|access-date=2021-08-18}}</ref>
