A most frequent misunderstanding. I couldn't have said it better than the people from buddhismnow.com:
Does Buddhism teach reincarnation?
Reincarnation is not a teaching of the Buddha. In Buddhism the teaching is of rebirth, not of reincarnation.
What is the difference between reincarnation and rebirth?
The reincarnation idea is to believe in a soul or a being, separate from the body. At the death of the physical body, this soul is said to move into another state and then enter a womb to be born again.
Rebirth is different and can be explained in this way. Take away the notion of a soul or a being living inside the body; take away all ideas of self existing either inside or outside the body. Also take away notions of past, present and future; in fact take away all notions of time. Now, without reference to time and self, there can be no before or after, no beginning or ending, no birth or death, no coming or going. Yet there is life! Rebirth is the experience of life in the moment, without birth, without death; it is the experience of life which is neither eternal nor subject to annihilation.

Unaccomplished activities of past lives are also one of the causes for reincarnation. Some of us reincarnate to complete the unfinished tasks of previous birth. This is evident from my own story of reincarnation:
“My most Revered Guru of my previous life His Holiness Maharaj Sahab, 3rd Spiritual Head of Radhasoami Faith had revealed this secret to me during trance like state of mine. This was sort of REVELATION.
HE told me, “Tum Sarkar Sahab Ho” (You are Sarkar Sahab). Sarkar Sahab was one of the most beloved disciple of His Holiness Maharj Sahab. Sarkar Sahab later on became Fourth Spiritual Head of Radhasoami Faith.
Since I don’t have any direct realization of it so I can not claim the extent of its correctness. But it seems to be correct. During my previous birth I wanted to sing the song of ‘Infinite’ (Agam Geet yeh gawan chahoon tumhri mauj nihara, mauj hoi to satguru soami karoon supanth vichara) but I could not do so then since I had to leave the mortal frame at a very early age. But through the unbounded Grace and Mercy of my most Revered Guru that desire of my past birth is being fulfilled now.”
Thank you, Anirudh Kumar Satsangi for your comment that is most appreciated.
Be well, Roger
Thank you very much, Dear Roger Le Marie for your kind words. I would like to quote some more views on rebirth and reincarnation.
Contrary to popular belief, reincarnation is not an exclusively Eastern notion but that has flourished in cultures around the world. It is still an integral part of some sects of the Jewish tradition; Kabbalistic Jewish wisdom tradition has reincarnation ideas embedded in it one way or another. Reincarnation is mentioned in numerous places throughout the classical texts of Jewish mysticism. “As long as a person is unsuccessful in his purpose in this world, the Holy One, blessed be He, uproots him and replants him over and over again”. (Zohar I 186b)
Gnostic and Early Christians also believed in reincarnation; only later on church removed all such texts and blended those heretics. History records that early Emperor Justinian in 545 A.D. was able to apply the full power of Rome and his authority to stop the belief in reincarnation. However, the Bible contain no condemnation of the principle of reincarnation, and in fact, when Christ was asked when Elijah would return, He answered that Elijah had returned, referring to John the Baptist. At one place it is also mentioned, “I tell you the truth, no one can see the Kingdom of God unless he is born again” (John 3:3).
Sakina Yusuf Khan writes in an article A Night Of Forgiveness published in The Speaking Tree: “It (Shab-e-Barat) is also a festival associated with the dead. It is believed that the souls of the dead are set free on this night to visit their relatives.” What this indicates? This is a belief in reincarnation, of course in subtle body. The Koran says, “And you were dead, and He brought you back to life. And He shall cause you to die, and shall bring you back to life, and in the end shall gather you onto Himself.” Among the followers of Islam, the Sufis especially believe that death is no loss, for the immortal soul continually pass through different bodies.
Austrian Scientist Rudolf Steiner says,
“Just as an age was once ready to receive the Copernican theory of the universe, so is our age ready for the idea of reincarnation to be brought into the general consciousness of humanity”.
