Sako 85 is a bolt-action rifle produced by the Finnish manufacturer Sako since 2006, and the name signifies that Sako celebrated 85 years that year. The model 85 is marketed as one of Sako's premium models for hunting, and is delivered in many different configurations and chamberings. According to Sako the rifle is available in over 1000 different configurations. Some examples are the Finnlight and Carbonlight models. Production ended at the end of 2022 for the newly introduced Sako 100.

Sako 85 is the successor to the Sako 75. The M75 and M85 designs have many similarities, but also many differences. While Sako 75 has push feed, Sako 85 has controlled feed. The two models also have different types of magazines, and some parts such as the bottom metals do not interchange.

The trigger pull weight is adjustable between 1–2 kg, and is delivered from the factory set to 1.5 kg. Sako 85 can also be delivered with a set trigger. The mechanism can be cycled with the safety applied. The bottom metal is made of aluminum for most of the M85 models, and is delivered in a color matching the receiver: Blued receivers are delivered with a black bottom metal, while stainless receivers are delivered with a grey bottom metal. The receiver has a proprietary integrated scope mount, which is a dovetail rail with varying width (narrower at the rear, wider at the front).

The Sako 85 is test fired at the factory with a 5-round group, which must satisfy a precision requirement better than 30 mm at 100 meters (0.3 mrad).

The rifle is delivered from the factory with a stock made of either walnut, laminate, plastic or carbon fiber, and with different shapes depending on the intended form of hunting or shooting discipline.

The receiver is made in 6 different lengths depending on the cartridge group. The rationale behind the large number of action lengths is to achieve a good fit with the cartridge length, and thereby avoiding an unnecessary long bolt travel, as well as weight reduction.
