From wikipedia:

"Antisemitism (also spelled anti-Semitism or anti-semitism) is hostility, prejudice, or discrimination against Jews.[1][2][3] A person who holds such positions is called an antisemite. Antisemitism is generally considered to be a form of racism.[4][5]

The root word Semite gives the false impression that antisemitism is directed against all Semitic people. However, the compound word antisemite was popularized in Germany in 1879[6] as a scientific-sounding term for Judenhass "Jew-hatred",[7][8][9][10][11] and that has been its common use since then.[12][13]"

Therefore, it is not the same as islamophobia.

A comparable word for muslims would be "anti muslim".
