地形图是一种以大比例尺及地形的定量表达为特征的地图。在过去制图时，可能用到很多不同的方法。现代制图则常使用等高线。对地形图的传统定义对天然和人造的地形特征都要进行表达。

地形信息中心（The Centre for Topographic Information）提供了地形图的定义：“地形图是用于表达地面的人文和自然特征的详细且准确的地图。（A topographic map is a detailed and accurate graphic representation of cultural and natural features on the ground.）”

In modern mapping, a topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features. A topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map. A contour line is a line connecting places of equal elevation.
