The 77th Regiment, Montgomery's Highlanders was a Scottish regiment of the French and Indian War, which was fought between Britain and her European and Indian allies and the French and her European and Indian allies on the continent and in the New World between 1757 and 1763.

The 77th was the first Scottish regiment raised specifically to fight in the rugged wilderness of North America, and was originally designated as "The First Highland Battalion of Foot." The Regiment fought with distinction along the western frontier, in what is now western Pennsylvania, at Fort Du Quesne and Bushy Run, in the Carolinas against the Cherokee allies of the French, and in Newfoundland, where they captured St. Johns.

Toward the end of the war, when most other regiments were safely and comfortably billeted as peacekeeping forces, six companies of the 77th were dispatched to the Caribbean, where they fought at Dominique, Martinique, and Havana, capturing them for the British crown.

At the conclusion of hostilities in 1763, the surviving officers and men of the regiment were offered land grants, the size depending on rank, in the New World. Many accepted the grants, and those who did not were transported back to Scotland
