That depends on the jurisdiction, and also on how exactly you define “lawyer.” (Do you mean someone with a law degree, or a member of the local bar association or some equivalent guild? The former is usually, but not quite always, a requirement for the latter.)
If anything, in many state and local jurisdictions within the U.S., judges are elected by popular vote, and I would guess that in some of those there are no such requirements for candidates, at least in theory.
Interestingly, for a U.S. Supreme Court appointment, a law degree from a top 14 law school (and at least one academic degree from Harvard or Yale) has been a de facto requirement for decades, but as recently as the 1930s and 1940s, there have been occasional SCOTUS justices appointed without a law degree at all.
Apparently the last United States Supreme Court Justice without a law qualification was Robert H. Jackson—although he passed the bar exam without official training and was a prominent practicing lawyer. I haven’t found the last time someone was appointed to that role without passing the bar but research so far does seem to suggest it is an entirely political position, without qualifications required.

They’ve all been lawyers, it’s just not an official requirement.
Presumably for the same reason there’s technically no official requirement that they be human, either.
That is, those with the power to appoint such judges would look like tools if they voted in non-lawyers or non-humans so they will not do either.
(It occurs to me there is a mutual exclusion joke in there somewhere.)
