The Battle on Vrtijeljka (Serbian: бој на Вртијељци, romanized: boj na Vrtijeljci) was fought on the hill of Vrtijeljka near Cetinje between a Venetian irregular force and an advancing Ottoman force on 7 May 1685 at the start of the Morean War. The Venetian force was made up of fighters from the neighbouring areas, including the band of acclaimed hajduk Bajo Pivljanin, and several Christian tribes. The large Ottoman force was led by sanjak-bey Süleyman of Scutari.
