Arukh HaShulchan is a work of halacha written by Yechiel Michel Epstein (1829–1908). The work attempts to be a clear, organized summary of the sources for each chapter of the Shulchan Arukh and its commentaries, with special emphasis on the positions of the Jerusalem Talmud and Maimonides.

Halakha, also transliterated as halacha, halakhah, and halocho, is the collective body of Jewish religious laws that are derived from the Written and Oral Torah. Halakha is based on biblical commandments (mitzvot), subsequent Talmudic and rabbinic laws, and the customs and traditions which were compiled in the many books such as the Shulchan Aruch. Halakha is often translated as "Jewish law", although a more literal translation of it might be "the way to behave" or "the way of walking". The word is derived from the root which means "to behave". Halakha not only guides religious practices and beliefs, it also guides numerous aspects of day-to-day life.
