The Ford Falcon (XF) is a full-sized car that was produced by Ford Australia from 1984 to 1988, with the utility and panel vans running through to March 1993. It was the third iteration of the fourth generation of the Falcon and also included the Ford Fairmont (XF)—the luxury-oriented version.

The XF sedan and wagon range was sold between October 1984 and February 1988.

In 1980, with high fuel prices in the wake of the 1979 oil crisis leading market sentiment in favour of smaller cars, Ford Australia planned to phase out the full-size, rear-wheel drive Falcon after the 1982 XE model. It was to be replaced by a smaller front-wheel drive car derived from the Ford Telstar/Mazda 626 platform, in a program dubbed Capricorn. However, the market success of the XD Falcon against the smaller Holden Commodore saw Bill Dix, who became CEO in 1981, cancel the program. Ford instead began development of the EA26 Falcon program, a new full-size, rear-wheel drive car range. The XF Falcon was conceived as an interim facelift for the XE Falcon until the all-new fifth-generation Falcon was ready to go on sale.

The XF Falcon continued the sales leadership of its predecessor. It remains Ford Australia's best-selling Falcon model ever with 278,101 built.

The production total was boosted by a prolonged run of the utility and panel van models. Ford had not developed an EA26 Falcon-based replacement for the XF commercial vehicle range, intending to discontinue it due to declining sales against commercial vehicles from Japanese makers which were up to 30 per cent cheaper. However, the strengthening of the yen against the Australian dollar in the mid 1980s eliminated the price advantage of the Japanese imports. This led to a sales revival for the Falcon commercial range such that by January 1987, Ford announced its intention to continue manufacturing the range. After five additional years of production, the XF commercial range was further updated into the 1993 XG and subsequent 1996 XH models, which sold alongside the fifth-generation Ford Falcon sedans and wagons.

XF models were available with a choice of 3.3 or 4.1-litre engine six-cylinder engines. The 4.1-litre unit was standard on Fairmont models.

Power and torque outputs for the carburetted 3.3 and 4.1 litre engines saw little or no change from the preceding XE series; engineering revisions were aimed at improving fuel economy and driveability. The 3.3 litre engine's maximum power and torque outputs remained at 90 kW (120 hp) and 240 N⋅m (180 ft⋅lb). Maximum power for the 4.1 litre engine decreased slightly from 105 to 103 kW (141 to 138 hp), while torque increased from 310 to 316 N⋅m (229 to 233 ft⋅lb)

The optional 4.1 litre EFI engine underwent a significant upgrade for the XF series, with a switch from Bosch Jetronic LE to Ford's EEC IV electronic fuel injection system. Maximum power output increased from 111 kW (149 hp) to 120 kW (160 hp), and maximum torque increased from 325 N⋅m (240 ft⋅lb) to 333 N⋅m (246 ft⋅lb). An XF Falcon S-Pack equipped with the EFI engine and four-speed manual transmission tested by Wheels magazine in 1984 accelerated from 0 to 100 km/h (62 mph) in 9.3 seconds, ran the standing 400 metres (0.25 mi) in 16.4 seconds, and ran to its 4500 rpm redline in fourth gear for a top speed of 190 km/h (118.1 mph). These performance metrics were only marginally behind the respective 8.9 seconds, 16.3 seconds and 194 km/h (120.5 mph) recorded for a 1982 XE Fairmont Ghia ESP equipped with a 5.8 litre V8 and four-speed manual transmission.
