"Nasrallah received Larijani and his accompanying delegation in the presence of Iranian Ambassador in Beirut Mohammad Fathali," Hezbollah said in a Tuesday statement.
The Monday meeting tackled recent developments in the region in general and Lebanon in particular, according to the release.
The statement did not reveal exactly when or where the meeting took place for "reasons of security."
Larijani arrived in the Lebanese capital on Monday from Damascus, where he had met with Syrian President Bashar al-Assad one day earlier.
Syria, Iran and Lebanon's Shiite Hezbollah movement – along with Palestinian faction Hamas – had all been part of a so-called "axis of resistance."
On the other side of the equation stood a U.S.-friendly "axis of moderation" that included Saudi Arabia, the United Arab Emirates, Jordan and Egypt (under then-president Hosni Mubarak).
Upon the outbreak of the Syrian uprising in 2011, Hamas refused to support the Syrian regime, straining relations between the two and prompting Hamas' leadership to decamp from Damascus, which for years had hosted the group's main headquarters.
The conflict in Syria, now in its fourth year, has continued to fuel sectarian tension inside Lebanon, with Hezbollah's ongoing military support for al-Assad's Alawite-dominated regime drawing condemnation from Sunni groups.
