Israel has stepped up strikes and deployed ground troops to its northern neighbour since March 2.
In a statement, the Lebanese army said that "as a result of an Israeli hostile raid" in the Nabatiyeh region, a soldier was injured and "died of his wounds", while four others were wounded.
An official from the military told AFP the soldiers had just finished their duties for the day.
Three Lebanese soldiers were killed by Israeli shelling earlier this month during a failed Israeli commando operation in eastern Lebanon.
