Slack Icon

Q: When should I use it instead of a similar icon?

Use it for send to Slack buttons on an alert, a report or a form response, posting to a chosen channel; the Slack row in integration settings, showing the linked workspace name once connected; and join our Slack links on a community, docs or open source project page. For channel names and hashtag chips in your own app's chat or feed, use the Hash icon. For team chat built into your own product, such as a comments or chat panel, use the Messages icon. For alerts in your own app, and the header menu that lists them, use the Notification icon.

Four rounded bars and four drop tabs in a pinwheel hash, the Slack logo, for team chat and notification integrations. Available in 4 styles (outline, solid, duotone and filled) as a React component you install with the shadcn CLI.

Which styles does it come in?

4 styles: Outline, Solid, Duotone and Filled. Every style is drawn on the same 24 by 24 grid and installs as its own file, so you can switch styles without touching the layout.

How do I install it with the shadcn CLI?

Copy the install command from the panel above, in the style you want, and run it in your project. The shadcn CLI adds the icon as a React component that you import and render like any other. It draws in the current text color, so your text color and size classes style it. Icon installs need a ReUI Ultimate license.

What icons go well with it?

Trello and Figma sit beside it in the same toolbar or menu. More from the same family and the Brands set: Android, Angular, Apple and Behance.

When was it added?

It joined the ReUI icon library on June 30, 2026.
