Haim Landau (Hebrew: חיים לנדאו, 10 September 1916 – 16 October 1981) was an Israeli independence fighter, Knesset member and Minister in the governments of Golda Meir and Menachem Begin.

Landau was born in Kraków, Austria-Hungary (today in Poland) and made aliyah to Mandate Palestine in 1935.

By 1940, he was a commander of the Betar branch in Haifa, and in early 1944 was transferred to Tel Aviv and appointed member of the General Headquarters by the end of year.

In 1947, he represented the Irgun, together with Begin and Shmuel Katz, at a meeting with the UNSCOP.

He was a member of the Begin cabinet, serving as Minister of Development in 1967–1970 and despite not retaining his seat in the 1977 elections, was made Minister of Transport by Menachem Begin, a role he retained until the 1981 elections.
