Is The Buddha Mentioned In Any Of The Hindu Scriptures?

Considering that the Vedas, Upanishads, and Bhagavad Gita were all written well before Siddhartha Gautama was alive, I'd say "no".

Not in the original works since Siddhārtha Gautama (the spiritual leader of the Buddhist thought) was not alive when they were written. However, since then the Hindu religion teaches that the Buddha was one of the ten Avatars of Vishnu. The Buddha was an incarnation to bring all the evil away from Hindu, the true religion. So there's a little animosity on that factor.

Buddha is commonly referred to as one of the reincarnations of Vishnu in modern editions of the Bhagavad Gita (at least its implied by virtue of illustrations)I believe there is also a common reference to him as the rider on the white horse, Kalki, in both Hindu and Buddhist texts.

NO. Hindu holy scriptures (Veda’s, Upanishad’s and Gita) doesn’t have any info about Buddha.

no, hindu scriptures don't have any information on a buddha or a " savior " of any kind

Buddha is not considered a God, he was just a very wise man .

yes, in some written after his birth but not in Vedas
