VP9 is an open and royalty free video coding format developed by Google. VP9 had earlier development names of Next Gen Open Video (NGOV) and VP-Next. VP9 is a successor to VP8. Its own successor, VP10, is currently under development. Chromium, Chrome, Firefox, and Opera support playing VP9 video format in the HTML5 video tag.

|Thanks||September: Microsoft announced in September 2015 that their Microsoft Edge browser will add VP9 support in future release.|
The development of VP9 started in the second half of 2011. The design goals for VP9 included reducing the bit rate by 50% compared to VP8 while maintaining the same video quality, and aiming for better compression efficiency than the MPEG High Efficiency Video Coding (HEVC) standard. In June 2013 the "profile 0" of VP9 was finalized, and two months later Google's Chrome browser was released with support for VP9 video playback. In October of that year a native VP9 decoder was added to FFmpeg, and to Libav six weeks later. Mozilla added VP9 support to Firefox in March 2014.
Throughout, Google has worked with hardware vendors to get VP9 support into silicon. In January 2014, Ittiam demonstrated its VP9 decoder on ARM Cortex devices. The Ittiam VP9 Decoder, built in collaboration with ARM and Google, focuses on balancing power, scale and portability requirements. It can decode 1080p at 30fps using the ARM Mali-T604 GPU on an Arndale board, powered by Samsung’s Exynos 5 Dual SoC. In early 2015 Nvidia announced VP9 support in its Tegra X1 SoC, and VeriSilicon announced VP9 Profile 2 support in its Hantro G2v2 decoder IP.
In April 2015 Google released a significant update to its libvpx library, with version 1.4.0 adding support for 10-bit and 12-bit bit depth, 4:2:2 and 4:4:4 chroma subsampling, and VP9 multithreaded decoding/encoding.
The VP9 format defines four profiles: profile 0, profile 1, profile 2, and profile 3. Profile 0 allows for a bit depth of 8-bits per sample and supports 4:2:0 chroma subsampling. Profile 1, which is optional for hardware, adds support for 4:2:2 chroma subsampling, 4:4:4 chroma subsampling, alpha channel support, and depth channel support. Google later developed two high bit depth profiles: profile 2 and profile 3. Profile 2 allows for a bit depth of 10-bits to 12-bits per sample and supports 4:2:0 chroma subsampling. Profile 3 adds support for 4:2:2 chroma subsampling, 4:4:4 chroma subsampling, and alpha channel support.

- YouTube offers several resolutions of VP9 video, with Opus audio in the WebM file format, through DASH streaming, including 720p and 1080p, and is now also using VP9 for 4K resolution content.
- Some smart TVs support VP9 (see list of 4K TVs).
- Android supports decoding VP9, from version 4.4 "KitKat" and newer.
- In September 2015, Microsoft announced the Edge browser in Windows 10 will add support for WebM/VP9.
On September 12, 2014, Google announced that development on VP10 had begun and that after the release of VP10 they plan to have an 18-month gap between releases of video formats. In August 2015, Google began to publish code for VP10.
