The 1986 Atlanta Braves season was the 116th in franchise history and their 21st in Atlanta.

• March 5, 1986: Rick Cerone, David Clay (minors), and Flavio Alfaro (minors) were traded by the Braves to the Milwaukee Brewers for Ted Simmons.^[3]

The Braves shutout the Montreal Expos, 6–0 in their season opener, but were 7–12 at the end of April, 6+1⁄2 games out of first. Atlanta won 17 of their first 25 games in the month of May, improving their record to 24–20 May 27. They were tied for second and were 1+1⁄2 games out of first.

On June 24 the Braves dropped into fourth place with a 34–36 record. They were in fourth place, 4+1⁄2 games out of first. Atlanta won seven of their next eight games to surge back into contention on July 3. Atlanta was 41–37 and in third place, 1+1⁄2 games out of first. The Braves promptly lost 20 of their next 25 games and fell into the cellar, 46–57, 12+1⁄2 games out of first. After a 12–5 run put them within 10+1⁄2 games of the lead, the Braves fizzled and faded down the stretch, losing their last five games to finish in last place with a 72–89 record, 23+1⁄2 games out of first.

The strong play of the Braves in the first half of the season was partly attributed to "The Bomb Squad", a group of six veterans who provided clutch hitting of the bench. The members of "The Bomb Squad" were: Ted Simmons, Chris Chambliss, Omar Moreno, Billy Sample, Bruce Benedict, and Andres Thomas.^[4] The name for the group was coined during spring training by Simmons in an effort to create unity among the bench players (Simmons, Moreno, and Sample were in their first season with the Braves).

• July 6, 1986: In an 11-8 loss to the Montreal Expos, Bob Horner hit four home runs in one game. Horner became the second player in the 20th century (Gil Hodges was the first in 1950) to hit four home runs in one game in his home park.^[5] He became the first player since Ed Delahanty to hit four home runs in a losing game.^[5]
