Not necessarily. Many people do this just to prevent clipping but in my opinion, if you practice proper gain staging, this shouldn't be an issue to begin with.
However, I do like to use a quick mastering chain or a limiter just for reference to give myself an idea of what it will sound like after the mastering to see if I need to change anything in the mix. At the end of the day, I take it off before I send it out to be mastered.
