Looney Tunes Platinum Collection: Volume 3 is a Blu-ray and DVD release by Warner Home Video. It contains 50 Looney Tunes and Merrie Melodies cartoons and numerous supplements. It was released on Blu-ray on August 12, 2014, and was released on DVD on November 4, 2014.

As per Jerry Beck's remarks during an episode of Stu's Show, it was indicated that Volume 3 would likely serve as the final installment of the series. This decision stemmed from the diminished sales figures of the Volume 2 in 2012 and the absence of a budget allocated by Warner Bros. for remastering the four films that had not been previously released on DVD and Blu-ray. Notably, the Blu-ray edition of this volume comprises only two discs, a departure from prior releases. A 12-page booklet akin to the one accompanying Volume 2 is included.

All cartoons released in this set are either an Academy Award winner or nominee or were listed in Jerry Beck's 2010 book The 100 Greatest Looney Tunes Cartoons. All but four cartoons — Honey's Money, Life with Feathers, Tree for Two, and Beep Prepared — had previously been restored as part of the Looney Tunes Golden Collection, the Warner Bros. Home Entertainment Academy Awards Animation Collection, or as part of a Looney Tunes Super Stars DVD. Of these four, three are new to Blu-ray and DVD, while one (Beep Prepared) had previously appeared unrestored as a bonus feature on the DVD release of Splendor in the Grass.
