; Saab 105
: Prototype. Two built.<ref name="Hewson p42" />
; SK 60A
: Two-seat jet trainer, liaison aircraft for the [[Swedish Air Force]].  149 built as SK 60A.<ref name= "Hewson p43">Hewson 1995, p. 43.</ref>
; SK 60B
: Two-seat attack version for the Swedish Air Force, modified from SK 60A with new weapons sight.<ref name="Hewson p43" />
; SK 60C
: Two-seat ground attack/reconnaissance version for the Swedish Air Force with extended camera nose.  One new-build prototype and 29 conversions from SK 60A.<ref name="Hewson p44">Hewson 1995, p. 44.</ref>
; SK 60D
: Saab had also designed the Saab 105 for use as a four-seat liaison transport: the two ejection seats could be removed and quickly replaced with four airline-type seats, with no provision for wearing a parachute, or four more austere seats that allowed the wearing of parachutes. In the mid-1970s, ten SK 60A aircraft were permanently configured as transports and given the designation of "SK 60D". Some were painted in the light green/dark green/tan [[Splinter pattern camouflage|"splinter" camouflage]] associated with the Saab Viggen fighter.<ref name="Hewson p45">Hewson 1995, p. 45.</ref>
; SK 60E
: This variant was a similar four-seat SK 60A conversion, but featured commercial-type instruments, including an [[instrument landing system]].  It was used to help train Flygvapnet reserve pilots in flying commercial aircraft. The SK 60E machines were eventually used as SK 60D liaison transports.<ref name="Hewson p45" />
; SK 60W
: In 1993, another upgrade program was initiated to modernize the SK 60, the most important improvement being fit of twin Williams Rolls FJ44 turbofans with 8.45&nbsp;kN (861&nbsp;kgp/1,900&nbsp;lbf) each and digital engine controls. The new engines provide more thrust, and are quieter, cleaner, and easier to maintain. The first Williams-powered SK 60—known informally as the "SK 60(W)"—performed its initial flight in August 1995.  About 115 conversions of SK 60A, 60B, and 60C aircraft were performed in the late 1990s. No conversions were performed of the SK 60D/E, with all such aircraft grounded and used as spares hulks.
; Saab 105XT
: Export demonstrator. An improved version of the SK 60B, re-engined with 12.68&nbsp;kN (2,850&nbsp;lbf) [[General Electric J85]] [[turbojet]]s. Prototype converted from second Saab 105 prototype.<ref name="Hewson p45-6">Hewson 1995, pp. 45–46.</ref>
; Saab 105D
: A refined business jet variant was considered, but the idea was out of date and there were no takers.<ref name="Hewson p42" />
; Saab 105G
: Revised version of 105XT with new avionics, including precision nav/attack system, more powerful J85 engines and modified wing. One converted from 105 XT prototype.<ref name="Hewson p47" />
; Saab 105H
: Proposed version for the [[Swiss Air Force]]. Never built.<ref name="Hewson p47">Hewson 1995, p. 47.</ref>
; Saab 105Ö
: Variant of the 105XT for the [[Austrian Air Force]], first delivered to [[Austria]] in July 1970. 40 built, delivered 1970–72, replacing the [[de Havilland Vampire]] and [[Saab 29 Tunnan]].<ref name="Hewson p46">Hewson 1995, p. 46.</ref>
; Saab 105S
: In the mid-1970s, Saab proposed yet another demonstrator, the "Saab 105S" for a Finnish trainer requirement, but the Finns decided to buy the [[BAe Hawk]] instead.<ref name="Hewson p47" />
