What is the name of the first iPad to support the Apple Pencil?

The first iPad to support the Apple Pencil was the 2015 iPad Pro.

Apple launched the original 12.9-inch iPad Pro in November 2015 alongside the first-generation Apple Pencil. The tablet was designed as a more powerful, spacious iPad for creative professionals and productivity users, while the Pencil added pressure and tilt sensitivity for drawing, handwriting, shading, and precise editing.

The first Apple Pencil paired and charged through a Lightning connector and included a removable cap. The original iPad Pro used a large Retina display, an A9X chip, and a Smart Connector for accessories such as Apple's Smart Keyboard. These features helped distinguish it from earlier iPad models, none of which supported Apple Pencil input.

The 2017 iPad was the first standard, non-Pro iPad to gain Apple Pencil support, which can cause confusion about the timeline. The iPad Air 2 and iPad mini 4 arrived before Pencil compatibility and did not support the original Apple Pencil.
