The Jämtland Ranger Corps (Swedish: Jämtlands fältjägarkår, JFK), is a Swedish Army infantry unit that operated in various forms during the years 1670–1983, 1990–1997, 2000–2005 and 2021–present. The unit was and is located in Östersund Garrison in Östersund.

The regiment had its origin in Ångermanlands, Medelpads och Jämtlands regemente raised in 1646 in the newly conquered province Jämtland, although the men were mostly recruited in the old Swedish provinces of Ångermanland and Medelpad. The regiment was also called Thomas Gärffelts regemente after its first commander.

The regiment was disbanded in 1661 as the recruitment provinces were transferred to the navy. But some companies of the regiment did exist until 1670, when they were incorporated in the newly raised Jämtlands regemente till fot (or Anders Plantings regemente). From 1689 on, the regiment was named Jämtlands dragonregemente, but had only one company of cavalry troops. This company was later organized into Norrland Dragoon Regiment.

The regiment was renamed Jämtlands infanteriregemente in 1770 before gaining the present name in 1820. The regiment also had the name Jämtlands fältjägarkår a short period between 1853 and 1892. Jämtlands fältjägarregemente was garrisoned in Östersund and was given the designation I 23 (23rd Infantry Regiment) after a general order in 1816. This was changed to I 5 in 1927. For a short time in the 1990s, the regiment was merged with the mobilization unit Fältjägarbrigaden before being reorganized in 2000 back to a separate existence as Jämtlands fältjägarregemente. The regiment ceased training conscripts in 2004, and was completely disbanded by August 2006.

Between 21 December 1687 and 15 August 1926, the regiment was trained at Frösö military camp. On 7 October 1905, the regiment's schools were moved to the Gamla skolan ("Old School") (Västra skolan, "Western School") at Rådhusgatan 44. In the autumn of 1910, the regiment moved into a newly established barracks at Fältjägargränd 13. The barracks were drawn by Erik Josephson, and was built after the 1901 military order's building program after Fortifikationen's design for infantry barracks. On 8 April 1911, the regiment commemorated the moving to Östersund through a moving ceremony. After the regiment was disbanded and commenced its decommissioning, the barracks area was left on 31 August 2006.

From 1687 to 1926, the regiment was based and trained at Frösö military camp. The regiment later trained at Grytans training area. The administration of the training area was under Norrland Artillery Regiment (A 4). After Norrland Artillery Regiment was disbanded in 1997, Jämtland Ranger Regiment took over the responsibility of the administration.
