The Viking B-8 Kittyhawk was an American single-engine open-cockpit biplane of the early 1930s.

Some aircraft were fitted with EDO floats for operation from water.

The Viking B-8 was flown by private pilot owners and by barnstorming firms who utilised the three-seat layout with a twin-passenger cockpit located ahead of separate pilot's cockpit.

In 2015 Viking Kitty Hawk Serial #28 was undergoing restoration to airworthiness following a landing accident in 1973.

[citation needed] Viking Kitty Hawk Serial #30 is in storage at New England Air Museum.
