This marks the second Iranian ballistic missile in the last week that has targeted the south of Turkey, which is a NATO military alliance member and Iran's neighbour.
Turkish officials had warned Iran against attacking again on Saturday but have not suggested the country wants to formally call on alliance members for further protection.
"We once again emphasise that all necessary measures will be taken decisively and without hesitation against any threat directed at our country's territory and airspace," the Turkish defence ministry said, adding some ammunition parts had fallen in the southeastern province of Gaziantep but there had been no casualties.
"We also reiterate that it is in everyone's interest to heed Turkey's warnings in this regard," it said.
It was unclear where the missile was headed before it was intercepted by NATO defences stationed in the eastern Mediterranean Sea.
US air forces are stationed at the Incirlik base in southern Turkey and there is a NATO radar base in Malatya province to the northeast that provides vital protection for the alliance.
Turkey said fragments from the missile fell in empty fields in Gaziantep, which sits roughly between the two.
Burhanettin Duran, President Tayyip Erdogan's communications director, said Turkey was strongly reiterating its warning to all parties, namely Iran, to avoid steps that endanger regional stability and civilians.
Turkey says that the United States has not used Incirlik in its air assault, alongside Israel, on Iran, which triggered Iranian missile and drone attacks.
Iran did not immediately comment on the incident but it has said repeatedly that it is not at war with regional countries and is not explicitly targeting Turkey.
Turkey, which had sought to mediate US-Iran talks before the air war that began last week, has previously said it had no intention of invoking NATO's Article 4 that would call allies to consult if a member is threatened.
That could lead to invoking the alliance's Article 5, which would call NATO to defend its attacked ally.
Turkey has the military alliance's second-largest army and has become a leading global actor in the defence industry in recent years.
However, it still lacks fulsome air defence of its own despite efforts to develop them.
It has relied on NATO's air defences in both incidents in the last week.
Meanwhile, the United Arab Emirates said 15 ballistic missiles and 18 drones were fired on the Gulf country on Monday.
That has brought the total projectiles fired at the UAE since the start of the US and Israel war against Iran to 253 missiles and 1440 drones, the UAE defence ministry said.
Four foreigners have been killed and 117 people wounded in the attacks, it said.
Israel said it had begun "a wide-scale wave of strikes" in Iran's capital Tehran, in Isfahan and in southern Iran.
It said the number of missiles launched from Iran in each barrage is decreasing.
In the early days of the war there were barrages with dozens of missiles but that has dropped to less than 10 or 20 missiles being launched at a time, Israeli military spokesman Lieutenant Colonel Nadav Shoshani.
Iran is still firing missiles frequently toward Israel, sending people running for shelter multiple times per day, especially in central Israel.
