Blaise Robert Alexander Jr. also known as BR Alexander (March 26, 1976 – October 4, 2001) was an American professional stock car racer from Montoursville, Pennsylvania. He began racing at the age of 12 in go-karts, winning the coveted World Karting Association East Regional championship in 1992. In 1995, he moved south to Mooresville, North Carolina, and drove in the ARCA Racing Series. Named ARCA's rookie of the year in 1996, Alexander was a regular driver in that series while also driving in both the NASCAR Busch Series and Craftsman Truck Series.

On October 4, 2001, during the ARCA EasyCare 100 at Lowe's Motor Speedway, Alexander's car crashed into the outside retaining wall nearly head-on. He died from a basilar skull fracture, the fifth driver death from rapid-deceleration head-and-neck movements in 17 months, convincing NASCAR to mandate the HANS or Hutchens devices for all drivers, despite the accident happening in ARCA.

Alexander was born on March 26, 1976, in Montoursville, Pennsylvania. He began his stock car career at age 12 in the World Karting Association and was the champion of the East Series in 1992. From that point, Alexander moved onto the Micro-Sprint racing series at tracks in different states including Pennsylvania, Ohio, and New York, posting a total of 48 wins in the series. In 1995, Alexander moved from Montoursville to Mooresville, North Carolina, to pursue a racing career.

At the EasyCare 100 at Lowe's Motor Speedway on October 4, 2001, Alexander was involved in a 2-car accident during lap 63 of the race. He was fighting for the lead position with Kerry Earnhardt for most of the race.^[1] During the lap, Earnhardt had to dodge a lapped car by hitting his brakes, which caused Alexander's No. 75 to catch up to Earnhardt's No. 2. Alexander began to inch into the lead when Earnhardt's car made contact with Alexander's, sending Alexander's car head-on into the wall and then back into Earnhardt's car, causing Earnhardt to flip over onto his roof and slide into the grass. After the wreck, Earnhardt got away unharmed, while Alexander was knocked unconscious.^[1] The ARCA race officials quickly threw out the red flag to send rescue workers onto the track to check on Alexander. Earnhardt had already gotten out of his car and wanted to go check on Alexander, a friend of his. Officials would not allow Earnhardt to see him and was taken to the infield care center. Alexander was pronounced dead at the infield care center at 10:20 PM. He was 25 years old.^[1][2] Alexander was interred at the Our Lady of Lourdes Catholic Church in his hometown of Montoursville, Pennsylvania.^[3]
