Donald Richard Donahue (May 18, 1942 – October 27, 2010) was a comic book publisher, operating under the name Apex Novelties, one of the instigators of the underground comix movement in the 1960s.

Donahue published numerous influential comics from that movement, including the first run of Zap Comix and a number of other highly regarded comics by Robert Crumb, such as Your Hytone Comics (1971) and Black and White Comics (1973).

Apex Novelties published the bulk of its comix from 1968 to 1974. Besides Crumb, other creators associated with Apex Novelties include S. Clay Wilson, Jay Lynch, Victor Moscoso, Art Spiegelman, Rory Hayes, Spain Rodriguez, Rick Griffin, Michael McMillan, Kim Deitch, Shary Flenniken, Justin Green, and Gilbert Shelton.

Donahue co-edited The Apex Treasury of Underground Comics, one of the first book collections to highlight the underground comix era.

In San Francisco in early 1968, Donahue traded his hi-fi tape player to poet Charles Plymell to publish the first issue of Robert Crumb's Zap Comix on Plymell's printing press. Donahue later purchased the equipment and founded Apex Novelties.

The publisher's first headquarters was in the third-floor ballroom of the former Mowry's Opera House, located at 633 Laguna Street in Hayes Valley (fellow underground publisher Rip Off Press also shared that space). While at that location, Donahue published some of the most notable — and notorious — comix of the underground era, including Zap issues #1-4, Snatch Comics issues #1–3, Cunt Comics, Jiz, King Bee, and The Life and Loves of Cleopatra.

After a fire almost destroyed the building in late 1969, Apex Novelties moved to a storefront at 1417 Valencia Street in the Mission District.

In 1970, Susan Goodrick became Donahue's partner in Apex Novelties, staying with the company until 1978. Also in 1970, Donahue helped Gary Arlington recruit artists for, and helped edit the first issue of, Arlington's anthology title San Francisco Comic Book.
