Pam Beesly and Jim Halpert
Affectionately dubbed “Jam” by fans of the show, Jim (John Krasinski) and Pam (Jenna Fischer) start out as just friends and coworkers, though it’s clear they’re meant to be more. After a lot of pining and a few major obstacles — including Pam’s engagement to Roy and Jim’s romance with Karen — they get together in season four, which later leads to a wedding and two kids. They face some growing pains in season nine when Jim takes a job in Philadelphia, but love and hard work keep them going.
