Receiver Eric Saubert executed the game-winning two-point play for Seattle.
Seattle staged a stunning fightback to defeat the Rams in extra time, securing their spot in the postseason.
Overcoming a 30-14 deficit in the final period, the Seahawks emerged victorious by a single point at home, registering their fifth consecutive win.
While the Rams had already secured a post-season berth earlier on game day, the Seahawks secured their place to the play-offs after a 24-month hiatus.
With this result, the Seattle now lead their division's race with a 12-3 mark, supplanting the Los Angeles, who dropped to the number five playoff position with an eleven and four record.
Quarterback Sam Darnold threw two interceptions but recovered to deliver two scoring throws, including the second score to wideout Jaxon Smith-Njigba in overtime.
The Rams held a six-point lead at the break before Walker broke free for a 55-yard touchdown run for Seattle.
Los Angeles cornerback Josh Wallace then took back Darnold's initial interception for a big return, setting up a one-yard score by Corum on the next play.
In the final stanza, a touchdown from Stafford to Puka Nacua pushed the advantage to sixteen points, but Rashid Shaheed provided the comeback with a spectacular punt return.
Darnold then connected with Barner in the end zone, and a successful two-point play forced the contest into an extra period.
Although Puka Nacua scored for his another TD in overtime, Jaxon Smith-Njigba responded in kind to set up the decisive score.
