The increases will apply only to the most expensive individual game tickets, primarily those closest to the field between the bases and in the club level - fewer than 1,000 tickets per game.
Season ticket prices and other individual ticket prices will remain the same.
"These seats are in the premium part of the ballpark and will not affect season ticket prices," Matthew Dryer, Orioles director of ticket sales, said.
"It helps us make a little extra revenue and rewards our regular season ticket holders."
The Orioles did not raise ticket prices following the 1998, 1999 or 2000 seasons, and a year ago the team raised some prices while lowering others.
The Orioles' total attendance of 2.68 million last season was the lowest in a non-strike-shortened season since the opening of Oriole Park at Camden Yards in 1992, and represented a 14 percent drop from 2001.
The team has finished fourth in the American League East for the past five seasons.
Ticketing is just one of the topics to be discussed at SportAccord, the leading industry conference taking place in Madrid between May 12-16.
