What is '`' character called?

Question

I feel silly for asking this but it isn't like I could google this.

What is the ` character called? In case it doesnt show up, it is the character used for inline code with markdown. Also, on most keyboards, it shares the key with ~.

I like all three answers so I made this a CW instead of accepting

Answer 1

Grave (pronounced Grahv, not like the synonym for tomb) or Grave accent.
