The HI environment of the Crab Nebula is investigated using 2.75' and 9'resolution data from (respectively) the DRAO Synthesis, and Effelsberg 100 m,radio telescopes. No clear evidence for an interaction between the Crab and thesurrounding HI is found; the Crab probably lies within the boundaries of alarge scale, low-density void in the HI distribution. The presence of awind-blown HI bubble near the Crab is confirmed, and it is suggested that theunidentified star which powers this bubble is responsible for the stellar windmaterial detected along the line of sight towards the Crab.
