市场划分协议（英语：Exclusive Territory）是一种由至少两间公司达成的销售协议。协议定明两所公司各自占据协议中指定的市场，目的是减少市场上的竞争。这种做法是反竞争行为之一，在不少国家，包括美国，均违反竞争法例。

市场划分协议较著名的例子为1987年，富美实（FMC Corporation）与旭化成化学（Asahi Chemical）两所公司就销售微晶纤维素达成协议。FMC公司后来更试图通过串通规模较小的竞争对手，消除市场上的竞争。

Dividing territories (also market division) is an agreement by two companies to stay out of each other's way and reduce competition in the agreed-upon territories. The process known as geographic market allocation is one of several anti-competitive practices outlawed under United States antitrust laws. The term is generally understood to include dividing customers as well.
