Illankai Tamil Arasu Kachchi (ITAK) (Tamil: இலங்கைத் தமிழரசுக் கட்சி, Sinhalese: ඉලංගෙයි තමිළ් අරසු කච්චි) is a Sri Lankan political party which represents the Sri Lankan Tamil ethnic minority in the country. It was originally formed in 1949 as breakaway faction of the All Ceylon Tamil Congress (ACTC). In 1972 ITAK merged with the ACTC and Ceylon Workers' Congress (CWC) to form the Tamil United Front, which later changed its name to Tamil United Liberation Front. ITAK remained dormant until 2004 when a split in the TULF resulted in ITAK being re-established as an active political party. ITAK is constituent party of the Tamil National Alliance.
