An Aerobie is a flying ring used in a manner similar to a Frisbee, for recreational catches between two or more individuals. The Aerobie differs from a Frisbee in that as a ring it is hollow in the middle, wheras a disc is solid. An aerobie is also lighter, and has better stability. Since it has much less drag and weighs less than a frisbee, it can easily be thrown several times farther than a frisbee.

It was used to achieve the Guinness World Record for the "longest throw of an object without any velocity-aiding feature". The record was originally set in 1986 and then broken in 2003 in San Francisco by Erin Hemmings. The 2003 record toss traveled 1,333 feet (406.3 metres) and the Aerobie was airborne for over 30 seconds. Designed in 1984 by Stanford engineering lecturer Alan Adler, the Aerobie has a polycarbonate core with soft rubber molded onto the inner and outer rims. The outer rim has a spoiler designed to impart stability. The AEROBIE® is available in two sizes. The AEROBIE® PRO RING is 13" in diameter, while the AEROBIE® SPRINT RING is 10" in diameter and is the best model for younger throwers or when one's throwing space is tight.

While the method of throwing an Aerobie is similar to a Frisbee, there are differences:

• As the Aerobie spends more time aloft, any errors in aim or technique imparted at the time of release will tend to magnify. This is particularly true when a slight angle off level is introduced at the time of release. It's quite easy to miss one's target by dozens of yards. The Frisbee, on the other hand, is somewhat self-correcting when the angle imparted is small.
• If one is only familiar with timing the trajectory of a Frisbee, judging how far and fast to run to catch an Aerobie will prove challenging (and humorous) initially. The mind will think the Aerobie will take a certain flight path based on the familiar behavior of a Frisbee, but the Aerobie will continue gliding, usually well over the head of the intended receiver.
• It is rare for a Frisbee to be caught in a tree. The disc design generally prevents it from becoming hung up in the branches. An Aerobie, given its ring design, can become trapped in a tree.
• The ring design of the Aerobie makes it much easier to catch by using an upward thrust of the arm.

Other Aerobie models include a triangular boomerang and smaller discs marketed at kids and dogs.

Aerobie golf, invented by Ronald Wend of St. Charles, Michigan, can be played by 2 or more people. Like Frisbee Golf, Aerobie golf can be played anywhere. Each game consists of 3 holes. One player or team will design the first game of 3 holes. A hole may be anything from hitting the trunk of a tree with your aerobie to landing it on some bleachers. Each throw is considered a stroke. The least amount of strokes to complete all 3 holes will win the game. The next team or player will then create the next game. The team or player who wins the most games will have won the match. Every player must throw from the same location at the beginning of each hole, but from there each player will throw from where their aerobie has landed. The player furthest from the hole will always throw first. The game designer throws first in each game. When playing in teams each player will throw their aerobie, but only the best throw from each team is played. The best throw is where all players from that team will throw next.
