Raymond Leo Jablonski (December 17, 1926 – November 25, 1985) was an American third baseman in Major League Baseball who played for all or parts of eight MLB seasons between 1953 and 1960.

A 1954 National League All-Star, Jablonski appeared in 812 games for the St. Louis Cardinals, Cincinnati Redlegs, New York / San Francisco Giants and Kansas City Athletics.

The native of Chicago, Illinois, threw and batted right-handed and was listed as 5 feet 10 inches (1.78 m) tall and 175 pounds (79 kg).

Although he led NL third-basemen in assists in 1954, Jablonski committed 27 and 34 errors in successive seasons, and with hard-hitting and slick-fielding Ken Boyer poised to break onto the varsity roster, the Cardinals traded Jablonski to the Redlegs along with pitcher Gerry Staley for Cincinnati relief ace Frank Smith after the 1954 campaign.

Jablonski was the Giants' regular third baseman during their final New York season and batted .289, but the following year he lost the starting job to rookie Jim Davenport and hit only .230 in part-time duty.
