Ilan Shalgi (Hebrew: אילן שלגי, born 13 July 1945) is an Israeli lawyer, politician and a former member of the Knesset.

After his national service in the IDF, in which he served as a lieutenant-colonel, Shalgi gained an LLB and an MA in law from Tel Aviv University.

In October 2004 he was appointed acting Minister of the Environment when fellow Shinui MK Yehudit Naot was suffering from cancer.

Following her death in November, Shalgi's position was made permanent, and he gave up the Science and Technology ministry.

He lost his seat when Hetz (the Secular Faction's successor) failed to cross the electoral threshold in the 2006 elections.
