Frohman died two months shy of his fifty-ninth birthday. His body was later washed ashore below the Old Head of Kinsale, and it was later determined that he was killed by a heavy object falling on him, rather than by drowning. His body lay among 147 others awaiting identification, where a rescued American identified him from newspaper photographs. His body, alone among all the others, was not disfigured. His funeral service was held on May 25 at the Temple Emanu-El in New York City, and he was buried in the Union Field Cemetery in Ridgewood, Queens, New York. Services were also arranged by some of his stars in other American cities: by Maude Adams in Los Angeles, by John Drew in San Francisco, by Billie Burke in Tacoma, and by Donald Brian, Joseph Cawthorn and Julia Sanderson in Providence, as well as memorial services at both St Paul's Cathedral and the Church of St Martin-in-the-Fields in London. Frohman was also eulogized by the French Academy of Authors in Paris.
