Rams wide receiver Demarcus Robinson is suing an L.A.-area hotel ... after he says the establishment didn't do enough to protect him during a terrifying robbery in its lobby last year.
The 29-year-old claimed in a lawsuit filed in Los Angeles County last week that the incident happened at the Lexen Hotel in North Hollywood at around midnight on Oct. 20, 2023.
Robinson claims he entered the facility through a side entrance after pulling into the parking garage ... but when he made his way into the lobby, two masked men pulled guns on him and threatened to murder him.
In the suit, Robinson says the men took nearly $150,000 worth of stuff off of his person during the encounter ... including a luxury diamond watch and two diamond chains.
Robinson claims the hotel didn't have security guards outside the hotel or in the lobby -- adding that employees who were working at the front desk at the time didn't call authorities until after the suspects had fled the area.

Robinson's suing the place for negligence and more ... seeking at least $149,500 in damages ... plus punitives.
Robinson played in 16 regular season games for the Rams this year. He also logged snaps in the team's lone playoff game earlier this month against the Lions, recording three catches for 44 yards.
Robinson did it all despite saying in his suit he suffered "an emotional toll" from the October incident at the hotel.
