Balloon Experiments with Amateur Radio (BEAR) is a series of Canadian-based amateur radio high-altitude balloon experiments by a group of amateur radio operators and experimenters from Sherwood Park and Edmonton, Alberta. The experiments started in the year 2000 and continued with BEAR-9 in 2012 reaching 36,010 metres (118,140 ft).

The balloons are made of latex filled with either helium or hydrogen. All of the BEAR payloads carry a tracking system comprising a GPS receiver, an APRS encoder, and a radio transmitter module. Other experimental payload modules include an Amateur Radio crossband repeater, and a digital camera all of which is contained within an insulated foam box suspended below the balloon. A parachute recovery system is automatically deployed when the balloon bursts at altitude.
