Thomas G. Thompson (T-AGOR-9) was a Robert D. Conrad-class oceanographic research ship acquired by the U.S. Navy in 1965.

The ship was transferred to the University of Washington for operation as part of the University-National Oceanographic Laboratory System (UNOLS) fleet on 21 September 1965.

The ship, placed out of service and struck from the register on 27 February 2004, was sunk as part of a NATO exercise 14 November 2004.

The initial vessel to be designated AGOR-23 was to "replace at least one existing AGOR 3 class ship in the Navy portion of the UNOLS academic fleet" with a part of the requirement being "a practical plan for return to the Navy of at least one AGOR 3 Class ship now chartered from ONR must be included in the proposal."

Gosport was retired, struck from the register 27 February 2004, and sunk in a NATO exercise on 14 November 2004.
