Nissan Slomiansky (Hebrew: ניסן סלומיאנסקי, born 1946) is an Israeli politician. He served as a member of the Knesset for the National Religious Party between 1996 and 1999, and again from 2003 until 2009 and was re-elected again in 2013
Slomiansky was born in Ramat Gan during the Mandate era. He was educated at Bnei Akiva's yeshiva in Nechalim and completed academic studies in physics and mathematics at Bar-Ilan University. He also studied in the Hesder Yeshivat Kerem B'Yavneh where he was certified as a teacher and ordained as a Rabbi. After his studies, he enlisted to the Nahal Paratroopers unit and reached the rank of first lieutenant. Thereafter he turned to politics, serving for more than two decades (1977–98) as the first head of Elkana local council. He was also the secretary-general of Gush Emunim.
In the 1996 elections, Slomiansky was placed 10th on the National Religious Party's list of candidates. He entered the Knesset in May 1997, following the death of Avraham Stern. He lost his seat in the 1999 elections, but regained it in 2003 when he was placed sixth on the party's list of candidates. He was later re-elected to the Seventeenth Knesset in 2006. During this period, he set a record for being the only member of Knesset to be present for 100% of the meetings and votes; likewise, he was known for being an extremely prolific legislator.
Slomiansky headed the parliamentary lobby for elderly persons during the Sixteenth Knesset. Since 2003 he is serving as the party's group chairperson at the Knesset, holding this position during the party's split on the background of the disengagement plan.
For the 2009 elections he won fourth place on the Jewish Home list, but lost his seat when the party won only three seats. In the 2013 election, he was placed third on the Jewish Home list and was re-elected to Knesset.
In 2011, Slomiansky was appointed Vice President of the Lander Institute, replacing Reserves-General Y. Amidror who was appointed to the Chief of Staff of the National Security Institute.
Slomiansky is married and a father of five.
