The palatal hook (  ̡) is a type of hook diacritic formerly used in the International Phonetic Alphabet to represent palatalized consonants. It is a small, leftwards-facing hook joined to the bottom-right side of a letter, and is distinguished from various other hooks indicating retroflexion, etc.

The IPA recommended that esh ( ʃ ) and ezh (ʒ) not use the palatal hook, but instead get special curled symbols: ʆ and ʓ. However, versions with the hook may have been used by some authors.

The palatal hook was withdrawn in 1989, in favour of a superscript j following the consonant (i.e., ƫ becomes tʲ).
