ApiaceaeCan you plant carrots and dill together?
Charts say no. Nobody has tested carrots with dill, as far as we could find. Both are in the Apiaceae family, so they share pests and diseases.
Why we can't give a firm answer
Garden charts advise against it. 2 garden chart entries say to keep them apart. None of them cites a source. Charts pass on gardening tradition; they are not tests.
List of companion plants (uncited entry) (Wikipedia)Same family, shared pests. Carrots and dill are both in the Apiaceae family, so the same pests and diseases can move from one to the other.

Harvest from the same space compares a bed with both crops against the same area split into single-crop beds, counting the harvest of both crops (the land equivalent ratio in yield trials).
