Twitter (renamed X in July 2023) supports all standard emojis, and these can be inserted via emoji keyboard or picker. Emojis can also be copied and pasted by choosing from the emojis on this page.

Twemoji was initially created in 2014 as an open source emoji project, created and owned by Twitter. However, following the privatization of Twitter in April 2022, the project appears to have been discontinued by X. The project has been continued as a standalone open source project by former Twitter staff alongside members of the Discord design team.

In February 2023 the Twemoji set ceased to be used by Twitter / X on mobile devices, replaced by the device's native emoji designs. After January 2024  the dedicated Twemoji website was also shut down (an archived version of the site from January 2024 can be seen here).

Emojis from Twemoji are found on the Twitter / X website (Twtter.com / X.com), X Pro (formerly TweetDeck), Twitter for Android, Discord, Roblox, and other apps. The Twitter / X app for iOS has always used the native emojis provided by Apple.

Hashmojis (previously known as hashflags, and later Custom Twitter emojis) are enabled for some events or promotions. These display on Twitter / X for a limited time, after specific hashtags.

While most emojis can be used in Twitter names, any emoji that resembles the verified checkmark is not permitted. See the list of emojis not permitted in Twitter / X names or bios.

Since 2021 glossy Twemoji Stickers began showing in select locations across Twitter, but as of early 2022 these glossy designs have yet to be used within the Twemoji emoji set. As of October 2022, these glossy sticker designs have been available for use within the Twitter mobile image editor and are featured within the platform's Twitter Status feature.
