Feyli (also Fayli or Faili) can refer to:

• Feyli, a group of Lor tribes located mainly in Lorestan.
• A general name used since middle of twentieth century by Iraqi Arabs for the southern dialects of the Kurdish language spoken in Iraqi Kurdistan and Iranian Kurdistan (i.e. the eastern part of Iraq in the Khanaqin region in the Diyala province near the Iraqi-Iranian border), Ilam province and parts of Kermanshah province in Iran by Feyli Kurds.
• Feyli is also used to refer to the northern dialect of Luri, spoken to the east of Khorram Abad.

Fayli, "Feili", or Feyli' (Kurdish: فه یلی /Feylî/Pehlî) are largely a Shi'a community living in Baghdad and the Diyala Province of Iraq around Khanaqin and Mandali, and then across the Iranian borders, into the provinces of Ilam, Kirmanshah and Luristan. They are an estimated 30,000 Faylis living in Iraq and Iran.

Feyli (på kurdiska Pehlí) är en av de sydliga dialekterna av det kurdiska språket. Eftersom Irak-Iran-gränsen delar upp Kurdistan går gränsen igenom feyliregionen, på grund av detta befinner sig feylikurder i södra delen av Kurdistan på båda sidorna om gränsen.
