政府商务办公室（The Office of Government Commerce）是英国财政部属下一个独立部门，功能和职权包括按照既定政策及工序支持政府及公营机构的采购及政府合约的谈判。其目的是在政府服务和采购方面加强对纳税人的问责性和效率。

政府商务办公室支持及鼓励政府和供应商加强关系，维持隐定的供应，也鼓励使用中小企业供应商和在政府采购中使用电子商贸。办公室在欧盟订定政府采购规则时代表英国政府参与。

大型英国政府合约则由办公室属下的 OGC Buying Solutions 负责。

2005年11月政府商务办公室开始按其 Commercial Activities Recompetition计划大规模改组，至今仍在进行中。

The Office of Government Commerce (OGC) was a UK Government Office established as part of the HM Treasury in 2000. It was moved into the Efficiency and Reform Group of the Cabinet Office in 2010, before being closed in 2011.

The OGC operated through the Government Procurement Service, an executive agency now known as the Crown Commercial Service.
