The Order of Prince Danilo I (Serbian: Орден Књаза Данила I, romanized: Orden Knjaza Danila I) is an order, formerly of the Principality and later Kingdom, of Montenegro; it is currently a dynastic order granted by the head of the House of Petrović-Njegoš, Crown Prince Nicholas.

It is awarded to prominent champions of the preservation of Montenegrin independence and for other humanitarian, scientific, artistic and pro-social achievements as defined by statute.

Alterations were made to the appearance of the original decoration created by Prince Danilo, and during the rule of King Nikola I Petrović Njegoš the order underwent two restructurings.

By 1922, the order consisted of five classes: Knight Grand Cross, Knight Grand Officer, Knight Commander, Knight, and Cross of Merit.

[1] Although no longer a state order, prominent Montenegrin officials—including President Filip Vujanović—have been appointed to the order.
