Hare Krishna is relatively new concept...it is not a Vedic practice.
@kaamdev810 -- It is mostly rooted in Vedas. Chaitanya Mahaprabhu popularized Hare krishna mantra, and lot of chanting, also ecstatic dancing. Chaitanya vaisnava order calls Krishna (not Vishnu, Narayana, Shiva, Durga, Ganesh, Ram, Hanuman) as the only real 100% Supreme God. I don't understand how because Krishna is supposed to be a Vishnu avatar. Also, Chaitanya is considered an avatar of Krishna.
They also glorify Radha as a super important character (as Krishna's energy) which is a relatively introduced characters. Vedas/Upanishads/Gita/Purans do not have Radha.
ISKCON does not care about worshipping anyone else except Krishna, Radha, Chaitanya, Chaitanya's disciple Nityananda, Jagannath (deity of Puri temple).
