The 32-year-old Diaz becomes a free agent.
Hinske, 33, signed a one-year deal with a team option for 2012. Terms of the deal were not immediately available.
Hinske hit .256 with 11 homers and 51 RBIs last season while playing left field, first base and third base. He provides insurance for rookie first baseman Freddie Freeman, the projected 2011 starter.
Hinske hit .298 (14-for-47) with three homers and 12 RBIs as a pinch-hitter.
Diaz spent most of his time with the Braves in a left-field platoon. The Braves recently acquired second baseman Dan Uggla from Florida. If third baseman Chipper Jones returns from knee surgery, Martin Prado is expected to move to left field.
Diaz was slowed by a right thumb infection in 2010, when he hit only .250 with seven homers and 31 RBIs.
His overall average for five seasons with the Braves was .305. He hit .338 in 2007 and .313 in 2009, when he set career highs with 13 homers and 58 RBIs.
