No it isn't. But the Talmudists think it is. The Talmud states it was even given to Moses which is patently false ... though it can never be proved. See what the Talmud says about itself:

The Talmudists' claim of divine revelation for their teachings appears in the following Talmudic passages: "Rabbi Abba said in the name of Samuel: For three year the House of Shammai and the House of Hillel were divided. Each one said the law is according to us. Then a voice came out from heaven and said: 'Both of these are the words of the living God.'" (Babylonian Talmud, Erubin 13b). "Rabbi Levy bar Chama said in the name of Rabbi Simeon ben Lakish: What is meant by the verse: 'And I will give you the tablets of stone, the law, and the commandment which I have written to teach them.' (Exodus 24:12). Tablets refers to the ten commandments; law refers to the Torah; and the commandment refers to the Mishnah; which I have written refers to the Prophets and the Writings; to teach them refers to the Gemara [=Talmud]. This teaches us that all of them were given to Moses at Sinai." (Babylonian Talmud, Berachot 5a). "When the Almighty revealed Himself at Sinai in order to give the Torah to Israel, he recited to Moses in due order the Scriptures, the Mishnah, the Talmud and the Aggadah [=Midrash]... Even that which a student asks his Rabbi, did the Almighty tell over to Moses at that time. After he learned it from the mouth of the Almighty he [Moses] said: 'Master of the universe! Let me write it for them.' He [the Almighty] replied: 'I do not wish to give it to them [entirely] in writing... but the Scriptures do I give to them in writing while the Mishnah, the Talmud, and the Aggadah I give to them orally.'" (Midrash Exodus Rabbah, Parashah 47).
