Gershayim (Hebrew: גֵּרְשַׁיִם, without niqqud גרשיים), also occasionally grashayim (גְּרָשַׁיִם), can refer to either of two distinct typographical marks in the Hebrew language. The name means "double geresh".

Gershayim most commonly refers to the punctuation mark ⟨״⟩. It is always written before the last letter of the non-inflected form of a word or numeral. It is used in the following ways:

Gershayim is a disjunctive cantillation accent in the Hebrew Bible: ◌֞. It is placed above the stressed syllable, as in Biblical Hebrew: וַיִּקַּ֞ח, romanized: wayyiqqáḥ, in Genesis 22:3.

Most keyboards do not have a key for the gershayim punctuation; as a result, a quotation mark is often substituted for it. The cantillation accent however is generally not typed, as it plays a completely different role and can occur in the middle of words (it does not mark any word separation), or marked using a different interlinear notation if needed (such as superscripts or other notational symbols).
