Samuel Richards, Jr. was an American open water swimmer who won the 1911 and 1912 Boston Light Swim. Richards won the 1912 race in a time of 5 hours 15 minutes as only 3 swimmers out of 42 entrants completed the race. He represented the L Street Swimming Club in Boston, Massachusetts and was a registered athlete of the New England Branch Amateur Athletic Union.
