The name Kaiser is a boy's name of German, Bulgarian origin meaning "Emperor". Kaiser is ranked #929 on our popularity charts and is often added to lists like German Shepherd Puppy Names and discussed in our forums with posts like "Safe, Brave or Guilty Pleasure".
From the experts:
Kaiser, as in roll and Wilhelm, appeared for the first time on the US Top 1000 in 2017. It fits the two-syllable -er ending style that's all the rage, and it lends itself to the short form Kai. But we hope this Germanic version of what is essentially a title rather than a name doesn't keep rising on the charts.
