Iran does not have many formal treaty-bound allies like NATO-style partners, but it does maintain a loose network of friendly states and armed groups that cooperate with it politically, economically, and militarily.

Core state partners

These are countries that generally have the closest strategic ties with Iran, even if they stop short of a formal defense alliance.

  • Syria – The closest regional state partner; Iran has backed the Syrian government militarily, economically, and with advisors for years, and the two coordinate closely on regional security and support for allied militias.
  • Russia – A major great‑power partner; Moscow and Tehran cooperate in Syria, arms sales, and energy, and share opposition to U.S. dominance in the Middle East, even though their interests are not always identical.
  • China – A key economic and diplomatic partner; China buys Iranian energy, has signed long‑term cooperation frameworks, and offers political cover in forums like the UN Security Council, but avoids being drawn into direct Middle East conflict on Iran’s behalf.
  • Iraq (Shia‑led governments) – Post‑2003 Iraqi governments have had deep ties with Iran through politics, trade, and security cooperation, especially via Shia parties and militias, even as Baghdad also works closely with the U.S.
  • Pakistan – A neighbor that cooperates with Iran on border security, trade, and energy, while balancing relations with Saudi Arabia and the U.S.; ties are pragmatic rather than an outright alliance.
  • India (limited but important) – Not an “ally,” but an important partner in energy and infrastructure (like the Chabahar port), trying to balance relations with both Iran and the U.S.

Non‑state allies and “Axis of Resistance”

Much of Iran’s real leverage comes from non‑state actors it supports, often referred to collectively as the “Axis of Resistance.”

  • Hezbollah (Lebanon) – Iran’s most important non‑state ally; receives funding, weapons, and training and coordinates closely with Tehran on regional strategy.
  • Hamas and Palestinian Islamic Jihad (Palestinian groups) – Iran provides weapons, funding, and training to factions that oppose Israel, though ties with Hamas have fluctuated over time.
  • Iraqi Shia militias – Groups such as Kataib Hezbollah and others receive support from Iran’s Revolutionary Guard and often act as its proxies against U.S. and allied forces in the region.
  • Houthis (Ansar Allah) in Yemen – Iran supplies political backing and varying levels of weapons and training; the Houthis’ missile and drone capabilities are widely linked to Iranian assistance.

These actors are central to how Iran projects power and “defends” itself indirectly rather than through formal alliances.

Friendly or balancing states

A number of countries are not formal allies but tend to lean away from U.S. pressure on Iran, cooperate economically, or take a more sympathetic diplomatic line.

  • Qatar and Oman – Gulf states that often act as mediators and keep working relations with Iran, even while hosting or cooperating with Western militaries.
  • Some Global South states – Various countries in Latin America, Africa, and Asia sometimes back Iran rhetorically in international forums or maintain sanctions‑busting trade, but they are not defense allies in a war scenario.

Important caveats

  • Iran has very few formal defense treaties ; its relationships are mostly informal, interest‑based, and sometimes fragile.
  • Major powers like Russia and China are partners, but they are cautious about being dragged into a direct military conflict on Iran’s side, especially against the U.S. and its allies.
  • Many Arab governments see Iran as a rival, even if some populations are sympathetic to Iran’s stance against Israel or U.S. influence.

In short, when people ask “which countries are allies of Iran,” the most realistic answer is a mix of a few close state partners (Syria, Russia, to a degree China and Iraq) plus a network of non‑state groups like Hezbollah, Iraqi militias, Hamas, and the Houthis that together form Iran’s de facto alliance system.
