When was the largest tsunami that ever hit hawaii?

1. I "think" it's the 1960 one. Quite a few people died on the Big Island and several more on the other islands.

   Search on google, that'll yield the best answers for you.

2. the 1960 tsunami had the highest recorded death toll, and was about 20 feet high. however, if you mean the largest by height, we don't know exactly how big the largest one was, but the molokai slide tsunami 1.4 million years ago probably caused a tsunami 2,000 feet high
