格兰扁山脉（Grampian Mountains）是苏格兰三个主要山脉之一，该山脉横跨苏格兰中部，成为苏格兰高地与苏格兰低地间的自然屏障。最高峰本尼维斯山（Ben Nevis）是英国最高的山。

The Grampian Mountains or Grampians (Am Monadh in Gaelic) are one of the three major mountain ranges in Scotland, occupying a considerable portion of the Scottish Highlands in northeast Scotland. The range extends southwest to northeast between the Highland Boundary Fault and the Great Glen, occupying almost half of the land-area of Scotland and including the Cairngorms and the Lochaber hills. The range includes many of the highest mountains in the British Isles, including Ben Nevis and Ben Macdui the two highest.
