The Dyke Delta JD-2 is an American homebuilt aircraft designed in the United States in the 1960s and marketed for amateur construction.

The wings can be folded for towing or storage and hinge upwards to lie flat above the fuselage, one atop the other.

In its standard configuration, the aircraft is a true double-delta with no horizontal stabilizer; however, a small T-tail is an option for trimming variants with higher-power engines.

Since the mid-1960s, designer John Dyke has sold full construction plans and three-view drawings for the aircraft to homebuilders and is still selling them today.

The delta configuration offers a relatively high cruise speed compared to conventional aircraft of the same weight and power.
