Where to start the Vinland Saga manga after the anime

Give it the last episode you watched. The mappings cover whole seasons. At a season boundary, the answer gives the next unread chapter; within a season, it gives a conservative starting point that may repeat material.

Every span the anime adapts

One row per season or film: the episodes, the chapters they adapt, and a note on where the boundary falls.

AnimeEpisodesChaptersNote
Vinland Saga Season 11–241–54Episode 24, 'End of the Prologue', takes its title from chapter 54, and season 2's first episode, 'Slave', from chapter 55, so the season ends exactly at the close of the prologue.
Vinland Saga Season 225–4855–100The farm arc. Episode 25, 'Slave', takes its title from chapter 55 and episode 46, 'Emperor of Rebellion', from chapter 97. Episode 48, 'Hometown', is Thorfinn's return in chapter 100, 'Homecoming', and goes on into the start of chapter 101, where he tells his family about Vinland, so a reader resuming at 101 repeats a few pages.
