The Eilat Mountains (Hebrew: הרי אילת Harei Eilat) are a mountain range within the southern Negev in southern Israel. The ranges of the Timna Valley belong to the Eilat Mountains. Among the central block of mountains, Mount Hezekiah is the highest, followed by Mount Solomon. The mountains overlook the Gulf of Aqaba, which is part of the Red Sea.

The rock formations in the Eilat mountains are a mix of granite, limestone, and sandstone, that can be described as "extremely colorful".

The mountain range is named after the nearby city of Eilat and the biblical name of the city Eilot (Eiloth), situated where today the city of Aqaba (Jordan) is located.

From the top of Mt. Tzfachot, in the southern tip of the mountain range, visitors may see Egyptian land (via the Sinai Peninsula) when looking southwestward. Visitors looking eastward, across the Gulf of Aqaba, may also see Jordanian land. On clear days, as well, Saudi Arabia can be seen, looking southeastward (also across the Gulf of Aqaba).

The ridge of the Eilat Mountains along the western side of the southern Arava Valley forms part of a 60,000 ha Important Bird Area (IBA), as designated by BirdLife International. This area is a vital migration route for over 420 bird species, especially during the spring and autumn migrations. Notably, 1.2 million raptors have been counted in a single spring season, underscoring the area's significance for bird migration. Bird species such as the European honey buzzard, black kite, Levant sparrowhawk, steppe buzzard, and steppe eagle are prevalent. The migration of great white pelicans and black storks is also significant in this region.

Mammalian inhabitants include the Desert pipistrelle (bat), lesser mouse-tailed bat, Arabian wolf, Blanford's fox , fennec fox, caracal, sand cat, Nubian ibex, mountain gazelle, and Dorcas gazelle.
