The 1958 Pittsburgh Steelers season was the franchise's 26th in the National Football League.

Despite the superior accommodations, the Steelers never in 1958 drew more than the 31,130 fans they brought out to their season opener.

After the second game of the season, Steelers coach Buddy Parker arranged a trade on October 6 that sent quarterback Earl Morrall and two draft picks to the Detroit Lions for quarterback Bobby Layne.

With optimistic expectations about the growth of the NFL, the Steelers moved to a new larger facility for the 1958 season, the University of Pittsburgh's Pitt Stadium.
