Torah study is the study by Jewish people of the Torah, Hebrew Bible, Talmud, responsa, rabbinic literature and similar works, all of which are Judaism's religious texts. Ideally within Judaism it is done for the purpose of the mitzvah ("commandment") of Torah study itself.

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

In rabbinic literature, the highest ideal of all Jewish men is Torah study, women being exempt from Torah study. 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. According to many historians, this carried over into the general characteristics of Jewish society, both religious and non-religious, down to the present. Some examples of traditional teachings:

Torah study is counted amongst the 613 mitzvot ("[Biblical] commandments"), finding its source in the verse (Deuteronomy 6:7): "And you shall teach it to your children," upon which the Talmud comments that "Study is necessary in order to teach." The importance of study is attested to in another Talmudic discussion (Kiddushin 40b) about which is preferred: study or action. The answer there, a seeming compromise, is "study that leads to action." Although the word "Torah" refers specifically to the Five Books of Moses, in Judaism the word also refers to the Tanakh (Hebrew Bible), the Talmud and other religious works, even including the study of Kabbalah, Hasidism, Mussar and much more.
