方位是各方向的位置。八方位指东、西、南、北，东南、东北、西南、西北，另四方指东南东、西南西、东北东、西北西、南南东、南南西、北北东、北北西，相对方位是前、后、左、右、上、下。

在地球球面上，顺着地球自转的方向为东方，逆着地球自转的方向为西方。

日出方位并不一定是正东方向，日落方向也并不一定是正西方向。如果太阳直射点在北半球，太阳从东偏北方向升起，从西偏北方向落下，太阳直射点纬度或当地纬度越高这个偏角越大。同理，如果如果太阳直射点在南半球，太阳从东偏南方向升起，从西偏南方向落下，太阳直射点纬度或当地纬度越高这个偏角越大。只有在春分和秋分时，太阳才是从正东方向升起，正西方向落下。

The four cardinal directions or cardinal points are the directions of north, east, south, and west, commonly denoted by their initials: N, E, S, W. East and west are at right angles to north and south, with east being in the clockwise direction of rotation from north and west being directly opposite east. Intermediate points between the four cardinal directions form the points of the compass. The intermediate (intercardinal, or ordinal) directions are northeast (NE), southeast (SE), southwest (SW), and northwest (NW). Further, the intermediate direction of every set of intercardinal and cardinal direction is called a secondary-intercardinal direction, the eight shortest points in the compass rose to the right, i.e. NNE, ENE, ESE, and so on.
