Siddur Im Dach (Hebrew: סידור עם דא״ח) is a Hasidic prayer book written by Rabbi Schneur Zalman of Liadi, the first Rebbe of the Chabad-Lubavitch movement. Accompanying the prayers are Hasidic discourses written by Rabbi Schneur Zalman.

The work was originally titled Siddur Tefillos MiKol HaShanah Al Pi Nussach HaAriZal, however it is commonly known by shorter titles such as Siddur Tefillos MiKol HaShanah, Siddur Im Dach and The Alter Rebbe's Siddur.

In the Chabad community, the Siddur refers to the standard prayerbook while Siddur Im Dach refers to the prayerbook with accompanying Hasidic discourses.
