Elias Victor Seixas Jr. (/ˈseɪʃəs/ SAY-shəs;[3][4] August 30, 1923 – July 5, 2024) was an American tennis player.

Seixas was born on August 30, 1923 in Philadelphia, Pennsylvania,[6] to Anna Victoria (née Moon), who was of Irish descent, and Elias Victor Seixas, who was born in the Dominican Republic,[7] of Dutch-Jewish descent.

[16][17][18][19] Seixas served as a pilot in the United States Army Air Corps during World War II for three years, which interrupted his tennis career.

[20][3][21] He then attended the University of North Carolina at Chapel Hill, where he was a member of Alpha Sigma chapter of the Chi Psi fraternity.

[20] In 1966, at 42 years of age, Seixas played 94 games over four hours to defeat 22-year old Australian Bill Bowrey, 32–34, 6–4, 10–8 at the 1966 Philadelphia Grass Championship.

Seixas is rated fifth in the category of most Davis Cup Singles matches (24), just behind Bill Tilden (25) and Arthur Ashe (27).

[32] Seixas was inducted into Class II of the Philadelphia Sports Hall of Fame in 2005.

[33] Afterward, he worked as a tennis director for the Greenbrier Resort in White Sulphur Springs, West Virginia and at a Hilton Hotel in New Orleans.

[34][35] He moved to California in 1989, where he lived in Mill Valley[3] and established a tennis program at the Harbor Point Racquet and Beach Club in Mill Valley (Marin County), now known as The Club at Harbor Point.

In 1998, unable to play tennis any longer due to his knees, he chose to become a bartender at Harbor Point.
