Alexander Zaïd (Hebrew: אלכסנדר זייד; Russian: Александр Зайд; 1886 – 10 July 1938) was one of the founders of the Jewish defense organizations Bar Giora and Hashomer, and a prominent figure of the Second Aliyah.

The orphaned teenager met Michael Helpern, a First Aliyah pioneer sent to Vilna to promote immigration to Palestine.

He worked at the winery in Rishon LeZion, where he met Israel Shochat, as a construction worker in Ben Shemen and a stonemason in Jerusalem.

In 1926 Zaïd moved to Sheikh Abreik in the Valley of Jezreel, where he worked as a watchman, overseeing the lands of the JNF.

The residents of the Arab village at the site had been evicted a few years earlier when the Sursuk family of Beirut sold the land.

On October 5, 2007, the statue of Alexander Zeid was toppled by unknown persons, and on December 31, it was fixed (the movie "Half Ton of Bronze" was based on the incident).
