Torah study is the study of the Torah, Hebrew Bible, Talmud, responsa, rabbinic literature, and similar works, all of which are Judaism's religious texts. According to Rabbinic Judaism, the study is done for the purpose of the mitzvah ("commandment") of Torah study itself.

This practice is present to an extent in all religious branches of Judaism, and is considered of paramount importance among religious Jews. Torah study has evolved over the generations, as lifestyles changed and also as new texts were written.

In rabbinic literature, a heavy emphasis is placed on Torah study for Jewish males, with women being exempt. This literature teaches an eagerness for such study and a thirst for knowledge that expands beyond the text of the Tanakh to the entire Oral Torah. Some examples of traditional religious teachings:

...the practical commandments are but a prelude to the intelligibles, and since the intellect is not constituted by them, there is no advantage in performing them

— Or Adonai

Torah study is counted among the 613 mitzvot (commandments), from the verse in Deuteronomy: "And you shall teach it to your children," upon which the Talmud comments that "Study is necessary in order to teach."

...the essence is to perform a Mitzvah at its correct time and with all of its detail and precision as an immutable decree and that purity of good thought should be attached to the performance then 'you will then go securely and both will be fulfilled in your hands. As the explicit Mishna taught that all for whom their actions are greater than their wisdom, then even their wisdom will be preserved in holiness, purity, and inspirational fervor and the comparison that Chazal make about this cannot be trivialized, that all whose actions are greater than their wisdom are like a tree whose leaves are few and their roots are many, that all the winds in the world cannot move it from its place and 'the one who hears will internalize'

— Nefesh haTzimtzum, Chaim of Volozhin
