Andrew John Yadao Seigle (born May 15, 1972) is a Filipino-American retired professional basketball player in the Philippine Basketball Association (PBA). He was also a member of the Philippine national basketball team. He is the brother of Danny Seigle, also a former basketball player in the same league.

In high school, Seigle led Carbondale to a Final Four in the state of Pennsylvania. He then spent his junior and senior years playing for the New Orleans Privateers as a reserve.

In the 1997 PBA Draft, at the age of 24 years old, Seigle was drafted #1 overall by the Mobiline Phone Pals. He was the first #1 overall pick be Filipino-American and the first to come from a non-Philippine school.

Seigle was considered one of the most dominant and best defensive players early in his PBA career. In his first three games, he scored no less than 20 points, a feat that wouldn't be matched by another rookie until Bobby Ray Parks Jr. did it in 2019. He would go on to win Rookie of the Year.

In 1999, Seigle was traded to the Purefoods Tender Juicy Hotdogs for Jerry Codiñera.

In 2001, he had his best scoring season with an average of 14.6 points.

From 2002 to 2003, Seigle couldn't play for the team as the Philippine Senate questioned his heritage.

In 2004, Seigle joined the Barangay Ginebra Kings.
