The 15 Best Characters That ‘ER’ Introduced Over 15 Season

Before Grey’s Anatomy broke its record in February 2019, ER was the record-holder for the longest American prime-time network medical drama, at 15 seasons and 331 episodes. 

For a decade and a half, the halls of Chicago’s County General Hospital saw countless faces come and go in triumph, tragedy, and everything in between, and so in honor of those fifteen seasons, we present the top fifteen ER characters. 

Jerry Markovic

Every procedural needs their comic relief to keep them from getting bogged down in the drama, and for ER, that person was Jerry Markovic (Abraham Benrubi). 

Dr. Robert Romano

Robert is, to put it bluntly, an abrasive asshole. But he is good at his job, and therefore is allowed to remain in a position of authority with little more than a slap on the wrist for each infraction. 

Dr. Doug Ross

It’s not an ER ranking without mentioning County General’s original good-looking bad boy Dr. Doug Ross (George Clooney). Everything about him was designed to make you weak in the knees. 

Haleh Adams

If the doctors of ER advocate for better healthcare for patients, it is Haleh who advocates for better treatment of those who spend their lives providing that ongoing healthcare and personal touch.
