The Sejil missile (Persian: سجیل, meaning "Baked Clay" (see Surat al-Fil of the Quran)), also known as Sejjil, is a family of Iranian solid-fueled ballistic missiles. The Sejil are replacements for the Shahab liquid-fueled ballistic missiles. According to US Pentagon sources, the missile profile of the Sejil closely matches those of the Ashura (Ghadr-110) and the Samen.

The Sejil is a two-stage, solid-propellant, surface-to-surface missile (SSM) produced by Iran with a reported 1,930 km (1,200 mi) range. A successful test launch took place on November 13, 2008. Its range, if confirmed, would allow it to strike targets as far away as Israel and southeastern Europe, though Iran asserts that it is intended for purely defensive purposes.

According to Jane's Information Group, details of the design other than the number of stages and that it uses solid fuel have not been released. Uzi Ruben, former director of Israel's Ballistic Missile Defense Organization, indicated that, "Unlike other Iranian missiles, the Sajil bears no resemblance to any North Korean, Russian, Chinese or Pakistani (missile technology). It demonstrates a significant leap in Iran's missile capabilities." Rubin went on to state that the Sejil-1 " ... places Iran in the realm of multiple-stage missiles, which means that they are on the way to having intercontinental ballistic missile (ICBM) capabilities ..."
