«Entidad sionista» (en árabe: الكيان الصهيوني) o «régimen sionista» (en persa: رژیم صهیونیستی) es un término que se utiliza principalmente en el mundo árabe  y en el mundo musulmán como un eufemismo peyorativo para referirse al Estado de Israel. La frase es utilizada como un medio de expresión hostil hacia Israel, rechazando el reconocimiento de su existencia, o negando su derecho a existir. Se ha descrito como una expresión que refleja el odio racial.
Antes de 1967, el término fue el estándar utilizado por los árabes para referirse a Israel, y fue particularmente popular en las emisiones oficiales de Egipto, Siria y Jordania durante las décadas de 1960 y 1970. El uso de este término ha persistido desde entonces. Ha sido utilizado, entre otros, por la Autoridad Palestina, la OLP, "Irán, el régimen de Saddam Hussein, por el Hamás" y "los embajadores de Siria e Irak ante las Naciones Unidas en los debates del Consejo de Seguridad en febrero y marzo de 2003, que precedieron a la invasión de Iraq."

ISBN 0-88738-647-4. «In this Arab world where faith and politics are linked, traditionalists and radicals, Saudis and Libyans, can unite in hostility against the state of Israel - whose right to exist they deny, whose very existence they refuse to acknowledge, whose name they refuse to utter, calling Israel instead 'the Zionist entity' or 'the deformed Zionist entity'.»

"Many Arab and Palestinian spokespeople have stopped calling the State of Israel by its name and have reverted to the expression 'the Zionist entity'. This can be understood as a return to questioning the very legitimacy of the existence of the state Israel."

"...the Israelis have suffered from repeated invasion, subjection to suicide-attacks, and the view that Israel was not a state like others. The various non-state names given to Israel in the Muslim world have been tokens of it. Of these the commonest—used by Iran, the Saddam Hussein regime, by Hamas, by the Lebanese Shi'ite movement, and many others—has been the term 'Zionist entity', or non-state. In 1991, during the Gulf War, the Iraqi army newspaper described Israel — avoiding its very name — as the 'bastard entity of the Zionists', to which it vowed 'complete annihilation'. The same term, 'Zionist entity', was used by both the Syrian and Iraqi ambassadors to the United Nations in the Security Council debates in February and March 2003, which preceded the invasion of Iraq."

"This pervasive denigration of Jews has been accompanied by a systematic denial of the Jewish state's legitimacy by both the PA and the PLO. Israel is often referred to by the pejorative phrase, 'the Zionist entity.' Israel is glaringly absent from Palestinian maps, which portray its territory as part of a 'Greater Palestine,' from the Jordan River to the Mediterranean."

To refer to it as 'Israel' is to acknowledge its existence as a legal entity."
