哈伯法（也称哈伯-博施法，德文：Haber-Bosch-Verfahren，英文：Haber Process，也称Haber-Bosch process或Fritz-Haber Process）是通过氮气及氢气产生氨气（NH₃）的过程。

氮气及氢气在200个大气气压及摄氏400度，通过一个铁化合物的催化剂（Fe），会发生化学作用，产生氨气。在这个情况下，产量一般是10-20%。

ΔH, 反应热为-92.4 kJ/mol。

选择高温的条件是为了提高反应速率，但因为此反应是放热反应，在此条件下平衡后的产率反而较低温时为低。

The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first half of the 20th century. The process converts atmospheric nitrogen (N₂) to ammonia (NH₃) by a reaction with hydrogen (H₂) using a metal catalyst under high temperatures and pressures:
