Aaron's Amphitheatre, Performing arts center at Lakewood Fairgrounds, Atlanta, US.

Aaron's Amphitheatre is an outdoor performing arts venue at Lakewood Fairgrounds in Atlanta with a covered stage and seating areas. The facility combines fixed seats in the covered section with open lawn space that extends capacity for large audiences.

The amphitheatre opened in July 1989 as the Coca-Cola Lakewood Amphitheatre, built for about ten million US dollars on the Lakewood Fairgrounds in Lakewood Heights. It is owned by the City of Atlanta and operated by Live Nation Entertainment. It reverted to Lakewood Amphitheatre in 2000, became HiFi Buys Amphitheatre in 2001, carried the Aaron's name from 2009 to 2015, and has been Cellairis Amphitheatre at Lakewood since November 2017.

Phish named it among their favourite venues, citing acoustics rarely found in lower-level roofed amphitheatres.

The venue sits about 4 miles south of downtown Atlanta, inside the Lakewood Fairgrounds. Of the 18,920 places, roughly 7,000 are fixed seats under the roof and about 12,000 are on the open lawn, so lawn ticket holders should plan for sun or rain. Parking is on the fairgrounds site.

Phish named the amphitheatre one of their favourite venues, citing acoustics rarely found in lower-level roofed amphitheatres. Linkin Park recorded "One Step Closer" from Projekt Revolution 2004 for their LPU 4 CD and "The Little Things Give You Away" from Projekt Revolution 2007 for LPU 7 at the venue.
