===Former offices===
* The [[Adaptive Execution Office|Adaptive Execution Office (AEO)]] was created in 2009 by the DARPA Director, [[Regina Dugan]]. The office's four project areas included technology transition, assessment, rapid [[productivity]] and [[adaptive system]]s. AEO provided the agency with robust connections to the warfighter community and assisted the agency with the planning and execution of technology demonstrations and field trials to promote adoption by the warfighter, accelerating the transition of new technologies into DoD capabilities.
* [[Information Awareness Office]]: 2002–2003
* The [[Advanced Technology Office (DARPA)|Advanced Technology Office (ATO)]] researched, demonstrated, and developed high payoff projects in maritime, communications, special operations, command and control, and information assurance and survivability mission areas.<ref>[https://www.militaryaerospace.com/communications/article/16709225/darpa-looks-to-ultrawideband-technology-for-advanced-tactical-networking/ DARPA looks to ultra-wideband technology for advanced tactical networking]

* The [[Special Projects Office (DARPA)|Special Projects Office (SPO)]] researched, developed, demonstrated, and transitioned technologies focused on addressing present and emerging national challenges. SPO investments ranged from the development of enabling technologies to the demonstration of large prototype systems. SPO developed technologies to counter the emerging threat of underground facilities used for purposes ranging from command-and-control, to weapons storage and staging, to the manufacture of weapons of mass destruction. SPO developed significantly more cost-effective ways to counter proliferated, inexpensive cruise missiles, UAVs, and other platforms used for weapon delivery, jamming, and surveillance. SPO invested in novel space technologies across the spectrum of space control applications including rapid access, space situational awareness, counterspace, and persistent tactical grade sensing approaches including extremely large space apertures and structures.
* The Office of Special Development (OSD) in the 1960s developed a real-time [[remote sensing]], monitoring, and predictive activity system on trails used by insurgents in Laos, Cambodia, and the Republic of Vietnam.  This was done from an office in Bangkok, Thailand, that was ostensibly established to catalog and support the Thai fishing fleet, of which two volumes were published.  This is a personal recollection without a published citation.  A report on the ARPA group under which OSD operated is found here.<ref>{{cite web |last1=Joanne |first1=Sandstrom |title=The United States and Thailand |url=https://digitalassets.lib.berkeley.edu/ieas/IEAS_12_0002.pdf |archive-url=https://web.archive.org/web/20210722140418/https://digitalassets.lib.berkeley.edu/ieas/IEAS_12_0002.pdf |archive-date=2021-07-22 |url-status=live |website=digitalassets.lib.berkeley.edu/ |publisher=Berkeley.edu |access-date=22 July 2021}}</ref> 
A 1991 reorganization created several offices which existed throughout the early 1990s:<ref>{{cite news| url=http://findarticles.com/p/articles/mi_6712/is_n27_v171/ai_n28601257/ | archive-url=https://archive.today/20120708012812/http://findarticles.com/p/articles/mi_6712/is_n27_v171/ai_n28601257/ | url-status=dead | archive-date=2012-07-08 | work=Defense Daily | title=DARPA restructures/creates new offices | year=1991}}</ref>
* The [[Electronic Systems Technology Office]] combined areas of the Defense Sciences Office and the Defense Manufacturing Office. This new office will focus on the boundary between general-purpose computers and the physical world, such as sensors, displays and the first few layers of specialized signal-processing that couple these modules to standard computer interfaces.
* The [[Software and Intelligent Systems Technology Office]] and the [[Computing Systems office]] will have responsibility associated with the Presidential High-Performance Computing Initiative. The Software office will also be responsible for "software systems technology, [[machine intelligence]] and software engineering."
* The [[Land Systems Office]] was created to develop advanced land vehicle and anti-armor systems, once the domain of the Tactical Technology Office.
* The [[Undersea Warfare Office]] combined areas of the Advanced Vehicle Systems and Tactical Technology offices to develop and demonstrate submarine stealth and counter-stealth and automation.

A 2010 reorganization merged two offices:
* The [[Transformational Convergence Technology Office|Transformational Convergence Technology Office (TCTO)]] and the [[Information Processing Techniques Office|Information Processing Techniques Office (IPTO)]] were combined in 2010 to form the [[Information Innovation Office|Information Innovation Office (I2O)]].
** TCTO's mission was to develop new crosscutting capabilities from a broad range of emerging technological and social trends, particularly in areas related to computing and computing-reliant subareas of the life sciences, social sciences, manufacturing, and commerce.<ref name="darpa.mil"/><ref>{{cite web |url=http://www.hpcwire.com/2010/09/22/embedded_clouds_a_look_back_at_hpec_2010/ |title=Embedded Clouds: A Look Back at HPEC 2010 |work=HPCwire |access-date=7 July 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150707185535/http://www.hpcwire.com/2010/09/22/embedded_clouds_a_look_back_at_hpec_2010/ |archive-date=7 July 2015 |date=2010-09-22 }}</ref>
** IPTO focused on inventing the sensing, networking, computing, and software technologies vital to ensuring DOD military superiority.<ref>{{cite web|url=http://schedule.sxsw.com/2014/events/event_IAP28839 |title=Schedule – sxsw.com |work=SXSW Schedule 2014 |access-date=7 July 2015 |url-status=live |archive-url=https://web.archive.org/web/20150909201234/http://schedule.sxsw.com/2014/events/event_IAP28839 |archive-date=9 September 2015 }}</ref>
