Lawrence Joseph Doyle (July 31, 1886 – March 1, 1974), nicknamed "Laughing Larry", was an American second baseman in Major League Baseball from 1907 to 1920 who played almost his entire career for the New York Giants.

He debuted with the Giants on July 22, 1907, arriving late after taking the wrong boat across the Hudson River; he cost his team the game with a ninth-inning error, though he also had a pair of hits.

He expected to be returned to the minor leagues; instead, he was retained by manager John McGraw, who named him the team's field captain in 1908 – a year in which he finished third in the batting race with a .308 average.

Doyle, who also became the roommate of Christy Mathewson for several years, followed up with a 1909 season in which he led the NL in hits (172) and was among the league's top four players in batting (.302), slugging (.419), home runs (6) and total bases (239).

He began 1916 with a .278 average before being traded to the Chicago Cubs in late August, a painful move for the fiercely loyal player who had famously said in 1911 that it was "great to be young and a Giant."

After hitting .395 for the Cubs in nine games that year, he batted .254 for the team in 1917, finishing fourth in the league with 6 home runs, before a pair of January 1918 trades brought him back to New York.

When the institution closed in 1954 due to the development of an effective antibiotic treatment, he was the last resident to leave; Life Magazine photographers covered his last meal and his departure, on foot, from the grounds.
