The grapheme Ř, ř (R with háček, example of Czech pronunciation:  ) is a letter used in alphabets of the Czech, Upper Sorbian languages and also in Kurdish languages when written in Latin script. It was also used in a proposed orthography for the Silesian language. A similar consonant can also be found in some Norwegian dialects (around Narvik), in Berber (especially in its Rif variety), and in some Spanish dialects as a variation of 'rr' (mainly Pastuso Spanish and some dialects in Ecuador).

The Unicode glyphs are U+0158 Ř and U+0159 ř . Either can also be represented using the combining character U+030C  ̌  COMBINING CARON.

In Czech it is used to denote [r̝], a raised alveolar non-sonorant trill. Its manner of articulation is similar to other alveolar trills but the tongue is raised; it is partially fricative. It is usually voiced, [r̝], but it also has a voiceless allophone [r̝̊] occurring in the vicinity of voiceless consonants or at the end of a word.

In Upper Sorbian, it denotes the voiceless postalveolar fricative [ʃ].

In Rif-Berber, the letter Ř / ř is used for /ɺ/, a sound between /l/ and /r/.

In Umbrian in transliterations of the native alphabet, it is used to designate a sound of unknown quality, generally deriving from earlier *d. The same sound is represented in the Latin alphabet by the sequence <rs>.

Czech: “Tři sta třicet tři stříbrných stříkaček stříkalo přes tři sta třicet tři stříbrných střech.”
