Ricardo Manuel Urbina (/ɜːrˈbiːnə/; January 31, 1946 – June 17, 2024) was a United States district judge of the United States District Court for the District of Columbia. The first Latino judge on the United States District Court for the District of Columbia, he was noted for his rulings in cases regarding terrorism during the George W. Bush administration, as well as for his ruling in District of Columbia v. Heller, which was later reversed on appeal and by the United States Supreme Court.

Urbina was born in New York City on January 31, 1946. He earned a bachelor's degree from Georgetown University in 1967. Urbina received his juris doctor from the Georgetown University Law Center in 1970. He began his legal career as a public defender. He worked for the Public Defender Service for the District of Columbia from 1970 to 1972 and was in private practice in Washington, D.C., from 1972 to 1974. He was on the faculty of Howard University Law School from 1974 to 1981.

In 1981, he became an Associate Judge of the Superior Court of the District of Columbia, nominated by Ronald Reagan, serving until his appointment to the United States District Court. He was the first Latino judge to be appointed to that court.

Urbina was nominated by President Bill Clinton on March 22, 1994, to a seat on the United States District Court for the District of Columbia vacated by Judge Aubrey E. Robinson Jr. He was confirmed by the Senate on June 15, 1994, and received commission on June 16, 1994. He was the first Latino judge to serve on the Court. He assumed senior status on January 31, 2011, and retired on May 31, 2012.

Urbina was assigned as the judge in Omar v. Harvey, in which Shawqi Ahmad Omar, an American citizen, captured and detained in Iraq by United States military forces operating as part of the Multi-National Force-Iraq, filed a petition for a writ of habeas corpus preventing the U.S. military from transferring him from U.S. military custody at Camp Cropper into the custody of Iraqi authorities for trial on terrorism charges in the Central Criminal Court of Iraq. Urbina issued an ex parte temporary restraining order requiring that Omar "not be removed from United States custody" and later converted the order into a preliminary injunction. The government appealed, and the D.C. Circuit, in a 2–1 decision, affirmed that the District Court had habeas jurisdiction under the U.S. Supreme Court precedent in Hirota v. MacArthur and that Omar's case could be reviewed because he had not yet been convicted by a foreign court. The case ultimately reached the U.S. Supreme Court, which heard this matter together with Munaf v. Geren, 553 U.S. 674 (2008). The Court unanimously affirmed Judge Urbina's conclusion that the habeas corpus statute, 28 U.S.C. § 2241(c)(1), extends to U.S. citizens held overseas by American forces subject to an American chain of command, even if acting as part of a multinational coalition, but also found that habeas corpus provided the petitioners with no relief because "habeas corpus does not require the United States to shelter such fugitives from the criminal justice system of the sovereign with authority to prosecute them."

In Rasul v. Rumsfeld (2006), Urbina found that British detainees at Guantanamo Bay could not bring a civil lawsuit against government officials under the Alien Tort Statute or the Geneva Conventions for alleged torture and mistreatment. Urbina did, however, find that the detainees could sue under the Religious Freedom Restoration Act for alleged restraints on their religious free expression. That later judgment was then reversed by the United States Court of Appeals for the District of Columbia Circuit.

Urbina presided over a number of habeas corpus petitions submitted on behalf of prisoners at the Guantanamo Bay detention camp. In October 2008, he ordered the release of a small group of Uighur detainees from Guantanamo into the United States because they are no longer regarded as enemy combatants.

On December 16, 2009, Urbina ordered Guantanamo captive "Saeed Hatim" to be released. According to Carol Rosenberg, writing in the Miami Herald Urbina's release order was sealed, and it "brought the so-called habeas corpus scorecard to 32 losses and nine victories by the Pentagon of detainee challenges from Guantánamo Bay, Cuba."^{[citation needed]} Dean Boyd, a Department of Justice spokesman, told Rosenberg the Government was reviewing its options in how to react to the ruling.^{[citation needed]}
