Tel HaShomer (Hebrew: תֵּל הַשּׁוֹמֵר, lit. Hill of the Guardsman) or Kiryat Krinitzi is a neighborhood in Ramat Gan, Israel. It borders Kiryat Ono in the north, Yehud in the east, and Or Yehuda in the south. A major Israel Defense Forces base and the Sheba Medical Center are located in Tel HaShomer.

Tel Litvinsky (later Tel Hashomer) was a moshava established in 1934 by Moshe and Emil Litvinsky in memory of their father Elhanan Litvinsky. The first inhabitants were Jewish immigrants from Germany and Poland. In 1936, it was noted for its high proportion of academics and doctors.

During World War II, most of the village lands were expropriated for the construction of a British military base. The base was of strategic importance because it controlled the Jaffa–Lydda Airport road. It was also used to house Italian prisoners of war.

On November 29, 1947, the Palmach stole explosives and 75 rifles from the camp. Towards of the end of the British Mandate for Palestine, Arabs under the command of Hasan Salama began smuggling in arms and personnel disguised as laborers into the camp. The Haganah command saw this as a threat and on April 15, 1948, two companies for the 32nd and 33rd Battalions of the Alexandroni Brigade entered and captured the base. Arab forces counterattacked from al-Khayriyya, Kafr 'Ana, al-'Abbasiyya and Saqiya, but the Jewish forces reinforced and pushed them back to a small salient in the south of the camp, which was captured later in Operation Hametz. The Alexandroni Brigade lost three soldiers, while the Arab losses were estimated at 50.

In 1948, the area was renamed Tel HaShomer after HaShomer, an early Ottoman-period Jewish defense organization.
