Haim Laskov (Hebrew: חיים לסקוב; 1919 – 8 December 1982) was an Israeli public figure and the fifth Chief of Staff of the Israel Defense Forces.

Haim Laskov was born in Barysaw in the Byelorussian Soviet Socialist Republic (present-day Belarus), to Moshe and Ita (née Hirshfeld) Laskov. He immigrated to Palestine with his family in 1925. The family settled in Haifa, where they lived in dire poverty.

Laskov joined the Haganah as a teenager, and served in various units, including Orde Wingate's Special Night Squads. He also served as a personal messenger for Yaakov Dori, who would later become the first Chief of Staff. In 1940, Laskov joined the British Army so that he could participate in World War II. He served in various capacities, and was an officer in the Jewish Brigade which saw action on the Italian front, eventually reaching the rank of major. After the war, he remained in Europe to participate in the Aliyah Bet illegal immigration effort to bring refugee Jews to Palestine. Along with other veterans of the Jewish Brigade, he also took part in extrajudicial executions of Nazi war criminals and their collaborators as vengeance for crimes committed against Jews. Upon eventually returning to Palestine, he rejoined the Haganah, while also working as chief of security for the electric company.

Laskov was married to Shulamit.

When the 1948 Arab–Israeli War erupted in 1948, Laskov assumed responsibility for preparing the framework in which new recruits would be trained. He organized the first officers' course, and formed the graduates into a brigade that fought at Latrun during Operation Nahshon. One month later, in May 1948, he returned to Latrun as commander of Israel's first armored battalion, which fought alongside the 7th Brigade. He commanded the entire brigade during Operation Dekel and Operation Hiram, and participated in the many battles over control of the Galilee. After the capture of Nazareth, he ordered the Palestinian population to be evacuated; this order was refused by brigade commander Ben Dunkelman. In July, he finally returned to training new recruits, now with the rank of major general.

Although he had never been a pilot, Laskov was appointed commander of the Israeli Air Force in 1951. During his tenure, the air force prepared to incorporate its first jet fighter, the Meteor. Upon completing his tenure in 1953, Laskov left the army to study philosophy, economics, and political science (PPE) in the United Kingdom. He also obtained additional military training there.

In 1955, he returned to Israel, where he was appointed Deputy Chief of the General Staff and Senior Staff Officer, however, after a series of professional disputes with Moshe Dayan, he was demoted to Commander of the Armored Corps. During the 1956 Sinai Campaign, he commanded the 77th Division, which operated on the Rafah–el-Arish–Kantara front. Upon the death of Asaf Simchoni, Chief of the Southern Command, in a plane crash, Laskov assumed his position, and oversaw the withdrawal of Israeli troops from the Sinai Peninsula.

In 1958, Laskov was appointed Chief of General Staff, replacing Moshe Dayan. His appointment took place against the backdrop of the unification of Egypt and Syria as the United Arab Republic on January 31 of that year and the potential threat this posed to the security of Israel. Just two months later, on March 30, Israel and Syria exchanged heavy artillery fire across the Sea of Galilee. The clashes lasted for two days, until a ceasefire was finally achieved.
