**Key words:** errata, addenda – galaxies: clusters: general – galaxies: evolution – galaxies: kinematics and dynamics – large-scale structure of Universe.

This is an erratum to the paper 'Mass calibration of the CODEX cluster sample using SPIDERS spectroscopy—I. The richness–mass relation' that was published in MNRAS, 486, 1594–1607 (2019). In the original version of this paper, Figs 3 and 4 referred to a different analysis carried out using X-ray luminosities instead of richness. The Figures have now been updated to reflect the results of the richness-mass calibration work. The author apologies for this error.
