I am creating a map using QGIS 3.12 and wish to rotate the map and add a grid using print composer, but I want to keep the grid unrotated.

Is this possible or does the grid only rotate with the map?

    that makes no sense - the grid is intimately related to the map's orientation – Ian Turton May 27 '20 at 12:44

    @IanTurton it is common to have a non-geographic grid to locate items (ex: letter A-E for columns, 1-10 for rows, then an index says "feature ABC: B-4") – JGH May 27 '20 at 12:49
  • I wish to retain the geographic grid, but I want to display it unrotated - it is projected so I don't think it necessarily relates to the map's orientation? – Chris May 27 '20 at 13:38
  • @JGH not sure I'd agree common but ok then cm will work – Ian Turton May 27 '20 at 14:22

If you use an interval in cm instead of map unit, then the grid will not be rotated enter image description here

  • do you need to set a specific EPSG for the grid or does this work for all CRS ? – J.R May 27 '20 at 13:26
  • @JGH thanks but I want to retain the geographical distance for the grid, I don't think this solution does? – Chris May 27 '20 at 13:36

    @Chris if you have a fixed scale you may calculate how many centimetre relate to the geographical distance you want to use for your grid and set that in the X and Y distance it's a bit of manual setting but better than nothing – J.R May 27 '20 at 14:57
  • @JGH yes that might be the only way, thanks for the idea. – Chris May 27 '20 at 15:10
  • else you would have to create a vector layer grid, with the opposite rotation – JGH May 27 '20 at 15:12

You could add another unrotated map on top of your rotated map, that follows a theme which shows no layers, and create the grid with the given scale in this dummy map.
