A subpoena duces tecum (pronounced in English /səˈpiːnə ˌdjuːsiːz ˈtiːkəm/ sə-PEE-nə DEW-seez TEE-kəm), or subpoena for production of evidence, is a court summons ordering the recipient to appear before the court and produce documents or other tangible evidence for use at a hearing or trial. In some jurisdictions, it can also be issued by legislative bodies such as county boards of supervisors.

The summons is known by various names in different jurisdictions. The term subpoena duces tecum is used in the United States, and some other common law jurisdictions such as South Africa and Canada. The summons is called a "subpoena for production of evidence" in some U.S. states that have sought to reduce the use of non-English words and phrases in court terminology.

The subpoena duces tecum is similar to the subpoena ad testificandum, which is a writ summoning a witness to testify orally. However, unlike the latter summons, the subpoena duces tecum instructs the witness to bring in hand books, papers, or evidence for the court. In most jurisdictions, a subpoena usually has to be served personally.
