Holosen Akhir atau Meghalayan adalah sub-kala ketiga dan terakhir dari kala Holosen, yang dimulai dari 4.200 SM hingga saat ini. Sub-kala ini ditentukan dengan kronostratigrafi, dan sudah memiliki GSSP (Global Boundary Stratotype Sections and Points).[1] Dimulainya subkala ini ditandai dengan peristiwa 4.2 kilotahun (kiloyear), yaitu sebuah peristiwa iklim, dimana iklim pada saat itu menjadi lebih kering.[2]
