Is Harry Potter's wand the Elder wand?

Harry Potter became the rightful master of the Elder Wand. The Wand belongs to the person who defeats its current owner. On the Astronomy Tower right before Dumbledore was killed, Malfoy disarmed him therefore becoming the rightful master. Later on, in a scuffle in Malfoy Manor, Harry obtained Malfoy's wand and became the owner of the Elder Wand without knowing.

Voldemort broke into Dumbledore's grave and stole the wand and tried to kill Harry with it, but because Harry was the wand's true master, the spell backfired and killed Voldemort.

Harry eventually decided the wand was too powerful and destroyed it, after using it just once to mend his own wand.
